The document provides information about graphing polynomial functions, including:
1) How to determine the degree, leading coefficient, intercepts, and behavior of a polynomial function graph from its standard and factored forms. Activities are provided to match polynomial functions and determine intercepts.
2) How to use the leading coefficient test to determine if a polynomial graph rises or falls on the left and right sides based on whether the leading coefficient is positive or negative and if the degree is odd or even. Examples analyze the behavior of specific polynomial function graphs.
3) How to sign a table to summarize the intercepts, degree, leading coefficient, and behavior of polynomial function graphs. Students are asked to graph specific functions and

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Sim(mathematics 10 polynomial functions)

Department of Education
Region III
Division of Zambales
ILEEN C. MENES
Don Marcelo C. Marty High School
2. Least Mastered Skill
Graph polynomial functions.
Subtasks:
Determine leading coefficient and degree of
polynomial functions
Identify y-intercept and x-intercepts of the
graphs of polynomial functions in factored
form
Describe the behavior of the graph of
polynomial functions using Leading
Coefficient Test
3. A polynomial function is a function such as a quadratic, a
cubic, a quartic, and so on, involving only non-negative integer
powers of x. We can give a general definition of a polynomial, and
define its degree.
A polynomial of degree n is a function of the form
f(x) = anxn + an-1xn-1 + …+ a2x2 + a1x + a0
where the a’s are real numbers (sometimes called the coefficients
of the polynomial). Although this general formula might look quite
complicated, particular examples are much simpler. For example,
f(x) = 4x3 – 3x2 + 2
is a polynomial of degree 3, as 3 is the highest power of x in the
formula. This is called cubic function.
Let us investigate on how to determine and graph
polynomial functions. Let’s try if the following activities can help us
to graph polynomial functions easily.
4. Get Connected….
Match Column A (polynomial functions in standard form) to Column
B (polynomial function in factored form. Connect same polynomial
functions using a line.
A B
y = x4 – 26x2 + 25 ● ● y = - (x +3)(x –2)(x–4)(x+1)
y = 2x3 – 7x2 – 7x + 12 ● ● y = - (x-1) (x+1)2 (x – 2)2
y = -x5 + 3x4 + x3 - 7x2 + 4 ● ● y = (x+1) (x-1) (x+5) (x-5)
y = x4 – 7x2 + 6x ● ● y = x(x – 1)(x – 2)(x + 3)
y = -x4 +2x3 +13x2 – 14x -24 ● ● y = (x-1) (2x+3) (x-4)
5. Seize and Intercept Me….
Determine the intercepts of the graph given its polynomial
function in factored form.
1. y = (x-1) (2x+3) (x-4) x-intercepts: __, __, ___
y-intercept: __
2. y = - (x-1) (x+1)2 (x – 2)2 x-intercepts: __, __, ___
y-intercept: __
3. y = x(x – 1)(x – 2)(x + 3) x-intercepts: __, __, ___, __
y-intercept: __
4. y = -(x+3)(x–2)(x–4)(x+1) x-intercepts: __, __, ___, __
y-intercept: __
5. y = (x+1) (x-1) (x+5) (x-5) x-intercepts: __, __, ___, __
y-intercept: __
Key points:
You can determine x-
intercepts by finding
the roots of the
polynomial function,
y = -(x-1)(x+4)(x-5)
Roots:
x-1=0; x=1
X+4=0; x=-4
X-5=0; x=5
however y-intercept
can be determined
by multiplying all
second terms of the
linear factors
-(-1)(4)(-5) = -20

12. Make Me Useful by Producing Something
Read the problem carefully and answer the question that
follow.
Because of the upcoming All Souls Day, you
are designing candle-making kits. Each kit contains 25
cubic inches of candle wax and a mold for making a
pyramid shaped candle with a square base. You want
the height of the candle to be 2 inches less than the
edge of the base
Questions/Tasks:
1. What should the dimensions of your candle mold be?
Show a mathematical procedure in determining the
dimensions.
2. Use a sheet of cardboard as sample material in
preparing a candle mold with such dimensions. The
bottom of the mold should be closed. The height of
one face of the pyramid should be indicated
3. Write your solution in one of the faces of your output
(mold)
How are
polynomial
functions used in
solving real-life
problems?
13. Intercepts and the Leading Coefficient Test
helped you a lot in graphing polynomial functions.
Also, we can use the concept of these to solve real-
life situations.
Summary:
If the degree is odd and the leading coefficient
is greater than 0, the graph will fall to the left and will
rise to the right. On the contrary when leading
coefficient is less than 0, it will rise to the left and fall
to the right. But if the degree is even, the graph will
both fall and rise on both sides depending on the
value of the leading coefficient.
