Question

Given an exponential function for compounding interest, A(x) = P(.82)^x, what is the rate of change?
a. –18%
b. –8%
c. 0.82%
d. 82%

Answer 1

Answer:

A is the correct answer.

Step-by-step explanation:

.82=1+r --> .82-1=1-1+r --> -0.18=r --> -18%

Answer 2

The rate of change is a. –18%.

Let r be the rate of change.

0.82=1+r

0.82-1=1-1+r

-0.18=r

=-18%

What is the exponential function?

An exponential characteristic is a mathematical characteristic of the following form: f ( x ) = a x. wherein x is a variable, and a is a constant called the bottom of the characteristic. The maximum usually encountered exponential-function base is the transcendental range e, which is the same as approximately 2.71828.
