Given an exponential function for compounding interest, A (x) = P (.82) x, what is the rate of change?

-18%

-8%

0.82%

82%

We are given the exponential function expressed as A (x) = P (.82) x and is asked in the problem the rate of change of the expression. In this case, the rate of change is 0.82 which is equal to 82 % in percentage. The answer hence to this problem is D. 82 %
