Neeed given an exponential function for compounding interest, a(x) = p(.82)x, what is the rate of change?

Answers

For the answer to the question above, it is -18% because to find rate we subtract the rate, in this case, is .82 or 82% - 1 or 100% and that would give you the rate, in this case, its decreasing by an 18%
I hope my answer helped you.

The rate of interest is 18%.

Step-by-step explanation:

The exponential function for the compound interest is A(x)=P(0.82)^x

That is, A(x)=P(1-0.18)^x

As we know,

The compound interest is given by A=P(1+r)^x, where r = rate of interest.

On comparing, we get that,

The rate of interest is 0.18 i.e. 18%.

Hence, the rate of interest is 18%.

D= 82%

just easier to see when at the top 😉

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 %
