1. 2.7 Absolute Value Functions and Graphs

2. 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.

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

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

8. Ex 1) Make a table and graph

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