Still using the function f(x) = ax\(\small\mathsf{ ^2 }\), how can we tell if the graph will be wider or narrower than the parent function? Click on the graphs to see the correct answer.

	If |a| > 1, then the function is vertically stretched and becomes narrower than the parent function. Take a look at the graph to the left.
	If |a| < 1, then the function is vertically compressed and becomes wider than the parent function. Take a look at the graph to the left.
