5.4 mathematical induction
The document discusses the method of mathematical induction. It is used to verify infinitely many related statements without checking each one individually. As an example, it examines the statement that the sum of the first n odd numbers equals n^2 for all natural numbers n. It shows the base case of this statement is true, and if the statement is true for an arbitrary n, it must also be true for n+1. Therefore, by the principle of mathematical induction, the statement is true for all natural numbers n.
Mathematical induction
Mathematical induction is a method of proof that can be used to prove that a statement is true for all positive integers. It involves two steps: 1) proving the statement is true for the base case, usually n = 1, and 2) assuming the statement is true for an integer k and using this to prove the statement is true for k + 1. Examples are provided to demonstrate how to use mathematical induction to prove statements such as the sum of the first n positive integers equalling n(n+1)/2 and that 7n - 1 is divisible by 6 for all positive integers n.

This document discusses linear equations in two variables. It defines linear equations, shows how to determine if an equation is linear and how to write it in standard form. It also discusses solving linear equations by finding ordered pairs that satisfy the equation. Finally, it demonstrates different methods for graphing linear equations on a Cartesian plane using tables of values, x- and y-intercepts, and slope-intercept form.
How to graph Functions
This lesson discusses graphing functions. It begins with examples of graphing functions given a limited domain by finding ordered pairs that satisfy the function and plotting the points. It then covers graphing functions with a domain of all real numbers by choosing values of x, finding corresponding y-values, plotting points to see a pattern, and drawing a line with arrowheads. The lesson shows how to use graphs to find function values and solve real-world problems by limiting domains to non-negative values.

This document outlines topics related to lines, parabolas, systems of equations, and exponential functions covered in Week 4 of a business mathematics course. Section 4.1 discusses lines and their slopes. Section 4.2 covers linear functions. Section 4.3 explains quadratic functions and how to graph parabolas. Section 4.4 presents methods for solving systems of linear equations. Section 4.5 discusses nonlinear systems. Section 4.6 defines exponential functions and their properties. Examples are provided throughout to illustrate key concepts.
Linear equations
The document discusses linear equations and graphs. It defines a linear equation as one where the variables each have an exponent of 1 and are only added or subtracted. It then identifies which of several example equations are linear based on this definition. The document explains that the graph of a linear equation is a straight line. It shows how to graph linear equations by making tables of values and plotting points. It also discusses how to graph vertical and horizontal lines when there is only one variable. Finally, it covers finding the equation of a line given its slope and y-intercept, or two points on the line.
Linear Equations in Two Variables.pptx
The document discusses linear equations in two variables. It will cover writing linear equations in standard and slope-intercept form, graphing linear equations using two points, intercepts and slope/point, and describing graphs by their intercepts and slope. Key topics include defining the standard form as Ax + By = C, rewriting equations between the two forms, using two points, x-intercept, y-intercept or slope/point to graph, and describing graphs by their slope and intercepts.
8.2 Equations W Two Variables
This document provides information about equations with two variables including:
- Examples of solving for y when given a value for x
- Real-life examples modeling temperature at different elevations
- How to graph linear equations by making a table of values and plotting points
- The vertical line test to determine if a relation is a function
Chapter11
This document provides information about graphing linear equations. It begins by defining a linear equation as one whose solutions fall on a straight line. It explains how to identify if an equation is linear based on whether a constant change in the x-value corresponds to a constant change in the y-value. The document then gives examples of graphing equations and determining if they are linear based on whether their graphs form a straight line. It also discusses using tables to list the x and y-values of points that satisfy the equation.
Straight line graphs
This document discusses straight line graphs and various methods for plotting straight lines on a graph. It covers identifying horizontal, vertical and diagonal lines, writing equations in y=mx+c form, using a table method to plot lines by substituting x-values, and using the x=0, y=0 method to find two points and plot a line from its equation. Exercises are provided for students to practice identifying and plotting different types of straight lines.
Mathematics 8 Linear Functions
This document provides a module on linear functions. It defines linear functions as those that can be written in the form f(x) = mx + b, where m is the slope and b is the y-intercept. The module teaches how to determine if a function is linear, rewrite linear equations in slope-intercept form, and graph linear functions given various inputs like two points, x- and y-intercepts, slope and a point, or slope and y-intercept. Examples and practice problems are provided to help students learn to identify, write, and graph different types of linear functions.

Graph of a linear function
- 1. GRAPH OF A LINEAR FUNCTION: NADEEM UDDIN ASSOCIATE PROFESSOR OF STATISTICS https://www.slideshare.net/NadeemUddin17 https://nadeemstats.wordpress.com/listofbooks/
- 2. *Graph of a linear function: The graph of linear equation is always a straight line. In order to draw the graph of linear equation better to assign at least 3 values of x and their corresponding value of y. The procedure is explained in the following example. Example Draw a graph of the linear function y = 2x + 4.
- 3. Solution: First of all we assign different values to ‘x’ and obtain the values of ‘y’. Let x = -2, -1, 0, 1, 2 x y = 2x + 4 y (x, y) -2 y = 2(-2) + 4 = -4 + 4 = 0 0 (-2, 0) -1 y = 2(-1) + 4 = -2 + 4 = 2 2 (-1, 2) 0 y = 2(0) + 4 = 0 + 4 = 4 4 (0, 4) 1 y = 2(1) + 4 = 2 + 4 = 6 6 (1, 6) 2 y = 2(2) + 4 = 4 + 4 = 8 8 (2, 8)
- 4. Now we plot the points
