Over which interval does the exponential show a more rapid rate of change?

Given an exponential function which is such that

f (-2) is about 0.2

f (-1) is about 0.4

f (0) = 1

f (1) = 3, and

f (2) = 9.

It can be noticed that the exponential function shows a more rapid rate of change over the interval 1 < x < 2.
