What is the result of vertically dilating a quadratic function by a factor of 2?

• The graph is wider

• The graph is skinnier

• The y-values are multiplied by 4

• The graph is moved up 2 units

How does a reflection of a quadratic function affect its graph?

• A reflection of a quadratic function has no effect on its graph

• A reflection of a quadratic function results in a parabolic graph with a different vertex

• A reflection of a quadratic function can result in an upside-down graph or a mirror image on the opposite side of the x-axis.

• The resulting parabola opens to the left.

What happens to the graph of an exponential function when it is dilated by a scale factor greater than 1?
