Question

If f(x) = 3x – 12, what is f(2)?

Answer 1

It would be B. -6.

f(x) = 3x-12
f(2) = 3(2)-12
f(2) = 6-12
f(2) = -6

Answer 2

B. -6

Explanation:

We are given

`f(x)=3x-12`

we have to find f(2)

To find f(2) , we can plug x=2 into f(x)

and we get

`f(2)=3* 2-12`

now, we can simplify it

`f(2)=6-12`

`f(2)=-6`

So, the value of f(2) is -6
