Which of the following did you include in your answer?
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.
