If f(x) = 3x – 12, what is f(2)?

Answer:
B. -6
Step-by-step explanation:
We are given
[tex]f(x)=3x-12[/tex]
we have to find f(2)
To find f(2) , we can plug x=2 into f(x)
and we get
[tex]f(2)=3\times 2-12[/tex]
now, we can simplify it
[tex]f(2)=6-12[/tex]
[tex]f(2)=-6[/tex]
So, the value of f(2) is -6
