8. Graphing Absolute Value
Notes p. 1
A function of the form f(x) = | mx + b | + c, where m≠0 is an absolute value function.
Let’s play in our calculator with graphing absolute value functions. Graph the following in your calculator, use the list function to plot points and sketch the graph.
Let’s do #1 together!
1. y = | x | -x x
