? The function f(x) = |x| is an absolute value function.

? The highest or lowest point on the graph of an absolute value function is called the vertex.

? An axis of symmetry of the graph of a function is a vertical line that divides the graph into mirror images.

An absolute value graph has one axis of symmetry that passes through the vertex.
