The graph on the left is the original y = x² and the one to the right is the transformed graph y = 4x² Notice that the distance between the parabola's sides has decreased or contracted.
What did we do to the coefficient of y = x² to make the graph contract?

So what do we do to y = x² to expand it? Think about this before checking the answer. A hint is we again need to alter the y value.
