Question

What is f(3) for f(x) = 3x + 2

Answer 1

f(3) = 11

Explanation:

f(x) = 3x + 2

In order to find f(3) substitute the value of x that's 3 into f (x) that's replace every x in f (x) by 3

That's

f(3) = 3(3) + 2

= 9 + 2

We have the final answer as

f(3) = 11

Hope this helps you

Answer 2

11

Explanation:

f(x) = 3x + 2

Let x = 3

f(3) = 3*3 +2

f(3) = 9+2

= 11
