MEDAL AND FAN!!! Given an exponential function for compounding interest, A(x) = P(.91)x, what is the rate of change?

OpenStudy (anonymous):

A. -0.09% B. -9% C. 0.91% d.91%

OpenStudy (anonymous):

it's C

OpenStudy (anonymous):

How would it be C? :o

OpenStudy (acxbox22):

no 0.91%=0.0091 i think it is B, because every time it decreases by 0.09 times(1-0.91=0.09)

OpenStudy (anonymous):

So it'd be -0.09 because its decreasing?

OpenStudy (acxbox22):

yes

OpenStudy (anonymous):

oh i see thank you :)
