Question

Main Idea: To evaluate an exponential growth or decay function, substitute a value for the exponent variable and simplify.

Evaluate each exponential function for the given value.

Answer 1

If there is more to the answer than what I give please ask for more!

With
`F(x) = 3^(x)` we can find
`F(4)` by substituting 4 into the main function.

So it would look like this:
`F(4) = 3^(4) = 3*3*3*3 = 81`

Hope this helps!
