2.7 Absolute Value Functions and Graphs

The simplest form of the absolute value function is written f(x)=|x| or y = |x|. This is called the parent function. Its v shaped and symmetric about a vertical line called the axis of symmetry. The highest or lowest point is called the vertex.

Ex 4) Without graphing, find the vertex, axis of symmetry, and transformations from the parent function.

Additional Example) Without graphing, find the vertex, axis of symmetry, and transformations from the parent function.

Ex 1) Make a table and graph

Ex 5) What is the equation of the absolute value function?
