Question

F(x) = 10x + 45, find f(1)

Answer 1

`f(1) = 55`

Explanation:

We are supposed to replace 'x' with 1 and then evaluate.

=====================================================

`f(x) = 10x + 45\\\rule{150}{0.5}\\f(1) = 10(1) + 45\\\\f(1) = 10 + 45\\\\\boxed{f(1) = 55}`

=====================================================

Hope this helps!
