Graph each absolute value function.

NOTES: y = a|x - h| + k

Vertex = (h, k)

AOS: x = h

Domain: x = All Real Numbers (-∞, ∞)

Range: if "a" is positive → y ≥ k

            if "a" is negative → y ≤ k

Comparison to Parent Function: "a" is vertical stretch

                                                      "h" is horizontal shift (left, right)

                                                       "k" is vertical shift (up, down)

Graph: Plot the vertex

Plot a point to the right by counting rise over run using the "a"-value

Plot a point to the left by counting rise over run using opposite of "a"-value
