The graph of an absolute value function has a vertex at (–2, 3) and passes through the point (–1, 0). using transformations of the parent function, has the graph been dilated by a scale factor other than 1? explain.

Yes, the graph has been dilated.

Using the standard form of the equation, substitute in the values: h = –2, k = 3, x = –1, and y = 0.

Solve the equation to get a = –3.

Graphically, the parent function follows the pattern of right 1, up 1. Moving 1 unit to the right from the vertex, you can move down 3 units to get to the point (–1, 0), so it has been horizontally compressed.

lockers 1, 4, 9, 16, 25, 40, and 49 are open
