Question

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

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!
