Question

A 2-column table has 4 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1. The second column is labeled f (x) with entries 0.004, 0.02, 0.1, 0.5.
What is the growth factor of the exponential function represented by the table?

0.2
0.1
5
20

Answer 1

Growth factor = f(x+1)/f(x). For example 0.02/0.004 = 5 (and 0.1/0.02 = 5, 0.5/0.1 = 5). So the growth factor is 5.
