It's one question I cant figure out. I called my friends and they don't get it.

f ( 2 ) = 3 x 2 = 6
f ( 0 ) = 3 x 0 = 0
f ( - 2 ) = 3 x ( - 2 ) = - 6

daveg1222 is right. Answers: f(x)= [x=2] 6, [x= 0] 0, and [x= -2] -6
All you have to do is multipy 3 with the number given for x.
Then put f(x)= whatever the answer is.

Try not to worry too much about what f(x) is in the real world, it doesn't matter to you yet. Think about it simply, f(x) is some number that depends on the value of x, so to find f(2) just replace the x's with 2's and find the value of f.
f(x) = 3 * x
f(2) = 3 * 2
f(2) = 6

f(2)=3(2)
f(2)=6
f(0)=3(0)
f(0)=0
f(-2)=3(-2)
f(-2)=-6
plug in the numbers for x then multiply the numbers and theirs your answer

just substitute the value of x then solve.
x=2
f(x) = 6
x=0,
f(x) = 0
x=-2
f(x) = -6
