Describe the graph of the function.

y = 5•2x

A The graph is a parabola with vertex (0, 5).

B The graph is an absolute value function with vertex (0, 5).

C The graph is of exponential growth.

D The graph is of exponential decay.

Looking at your choices, I believe that you meant to write that 2 is to the power of x. This is the typical form.

In this case, the correct answer would be choice C. It is an exponential equation, that is starting at 5 and increasing by a factor of 2.
