Question

Decide whether the function is an exponential growth or exponential decay function, and find the constant percentage rate of growth or decay. (5 points)
f(x) = 4.7 ⋅ 1.09x


Exponential decay function; 109%

Exponential growth function; 0.09%

Exponential growth function; 109%

Exponential growth function; 9%

Answer 1

If 1.09 is greater than 1.00, its considered a `growth` function. If its less that 1.00, its considered a `decay`. Based on this information, is the function a growth or a decay?

no, that is incorrect

Answer 9

damn.

Answer 10

To find the rate, we can see how far from 1 is 1.09? Please do this <

Answer 11

.09

Answer 12

mhm so then what is .09 as a percent? Remember to move to the decimal 2 places to the right to find the percent (:

Answer 13

9%

Answer 14

Yes, so you have a growth by 9%
