Just replace all occurrences of the variable (e.g. x, n) with that number and simplify. For example,
 = 2x^3 + 5x + 1)
 = 2(1)^3 + 5(1) + 1 = 8)
Things get a little different when the function is not in terms of a simple "x." We can define a function g:
 = 5x^2)
Suppose we want to find the value of g(7). We do not plug in x = 7. Rather we plug in 2x + 1 = 7, which is the same as plugging in x = 3.
 = 5(3)^2 = 45)
