This document provides instructions for graphing polynomial functions. It discusses the seven steps to graphing polynomials: 1) determining end behavior, 2) finding x-intercepts, 3) finding the y-intercept, 4) determining symmetry, 5) finding maximum turning points, 6) finding extra points, and 7) drawing the graph. It then discusses circles and their parts, including the circle, radius, diameter, chord, secant, and tangent. Examples are given of circles in everyday life.

Step 1: Determine the graph's end behavior.
Step 2: Find the x-intercepts or zeros of the function.
Step 3: Find the y-intercept of the function.
Step 4: Determine if there is any symmetry.
Step 5: Find the number of maximum turning points.
Step 6: Find extra points, if needed.
Step 7: Draw the graph.

14. The Circle and
Its Parts

15. Objectives:
◎ Identify the parts of a circle
◎ Illustrate a circle and the term
related to it: center, radius,
diameter, chord, secant and
tangent

16. Essential Questions:
What are the different parts
of a circle and its
corresponding definitions?
How do we use circles in
everyday life?

1 Circle
set of all points on a given plane that is equidistant from
a fixed point on the plane called the center of the circle;
named based on the letter used to indicate the center of
the circle

19. 19

20. 20
2 Radius
distance between the center of the circle and a point on
the circle; the plural form of radius is radii

21. 21

3 Diameter
a chord that passes through the center of the circle; the
diameter is also the longest chord in a circle

23. 23

24. 24
4 Chord
a line segment whose endpoints lie on the circle

25. 25

5 Secant
a line that intersects a circle in two points

6 Tangent
a line that intersects a circle at only one point; the point
where it intersects the circle is called the point of
tangency

““An electronic and communication
engineer designed a circular disk to be put
up in DJAPMNHS’ campus for
communication purposes in the whole
Division of Batangas. Before he installs the
disk, he left his men check the disk and its
parts. Supposed I am the engineer and you
are my working men, what are now the
parts of the circular disk? Identify the
radius, chord, diameter, secant and tangent
given the figure.”

Let’s Practice!
On a ¼ sheet of paper, draw a circle with
center B, with two diameters namely
segments AC and DF, whose chords are
AC, DF, CF, and DG, a secant HI, and
tangent JK intersecting at point A.

(Journal Writing)
Circles are still symbolically important today.
They are often used to symbolize harmony and
unity. As a person, how can you promote
harmonious relationship to your family, school
and community. Write a short essay about this
and create a unity symbol of your own using
circles. Then, post it in your personal Facebook
account with the #ilovemath.
