Question

Evaluate the following function at f(15)Type the numerical value for the answer

Answer 1

To evaluate a function, you can substitute x with the value given. So, to evaluate f(15) of the function

`f(x)=4(-2)^{(x)/(5)}`

We do:

`f(15)=4(-2)^{(15)/(5)}=4(-2)^3=4(-8)=-32`

Then:

`f(15)=-32`

To evaluate f(24) we do the same:

`f(24)=4(-2)^{(24)/(5)}`

The problem here is that 24/5 isn't an integer. So we can stop here.
