If f(n) = 5^n
then f(1) = 5^1 = 5
just replace all the n's with whatever you want. If that's numbers, then you can evaluate the result.
f(n) = -n
f(-3) = -(-3) = 3
and so on.

So, I just replace the letters with whatever number I want then I evaluate? How do I evaluate?
oh come on. I showed you two examples. Surely you can do arithmetic.
