Give the function f(x) = 25x + 2x + 9 find f(1) and f(2)

Assuming you didn’t intend on squaring the x attached to the 25, this problem is pretty easy. Firstly, just simplify the problem altogether. So add the 25x and 2x to get 27x since they are common factors. The way to find f(1) and f(2) is literally just substituting the numbers 1 and 2 into the equation. For f(1), the equation is 27(1)+9 which is a final answer of 36. And the second equation, f(2), is 27(2)+9 which is then 63.

F(1)=36
F(2)=63
