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?

The answer is C

Step-by-step explanation:

Because!

Solution:

It is given that , number of members f(x) in Joe's health club increased by 25% every year over a period of x years.

The relationship between f(x) and x is given as:

Replacing f(x) by y, in the above equation

y=

To draw the graph without the help of Desmos, find diifferent value of y, for different values of x, For example , for x=1

We get , y= = 18.75

For, x=2

y=   =15 × 1.5625=23.4375

For, x=3

y= = 29.296875

So, for different values of x, we get different values of y. Mark these points in the coordinate plane, and join them . You will get the graph of the above function :⇒ f(x)=
