Question

If f(x) = 3 x + 2

What is f(5)?​

Answer 1

17

Explanation:

The given equation is

f(x) = 3x +2

Then it asks you to find f(5). Since 5 is inside the parentheses, it is asking for what f(x) equals when x = 5.

In order to solve, simply plug in 5 into the x-values of f(x).

f(5) = 3(5)+2 = 15 + 2 = 17
