Answer 1

9514 1404 393

Answer:

decay; 8% decrease per time period

Explanation:

The growth factor is the base of the exponential term. The growth rate is 1 less.

growth rate = 0.92 -1 = -0.08 = -8%

When the growth rate is negative, it is exponential decay withe the amount of decrease equal to the magnitude of the rate.

A growth rate of -8% represents exponential decay, with a decrease of 8% per time period.
