The number of members f(x) in joe's health club increased by 25% every year over a period of x years. the function below shows the relationship between f(x) and x: f(x) = 15(1.25)x which of the following graphs best represents the function?

initial value is 15

growth factor is 1.25

Step-by-step explanation:

we are given

The number of members f(x) in Joe's health club

increased by 25% every year over a period of x years

The function below shows the relationship between f(x) and x as

now, we can compare it with exponential function

where

a is the initial value

b is growth factor

we can compare and find 'a' and 'b'

So,

initial value is 15

growth factor is 1.25

we know that

x is time

so, it can never be negative

f(x) is number of chambers

so, f(x) can not be negative

now, we can draw graph

and we get as

Sorry for no help, but I know which graphs he is talking about. The correct one would be the one that starts at 15 on the y axis, and then goes 75 at 7 years.
