Gosh never answered a simpler question!
Given: f(x) = - x - 4
To get f(x), Put x value as 3.
Therefore, f(3) = - 3 - 4 = -7.

To find f(3) sub in 3 into the equation as the variable (x).
So f(3)= -(3)-4 = -3-4 = -7

just plug in 3 for x in the equation...
f(3)=-3-4
f(3)=-7
so the answer is f(3)=-7
hope this helps

since they define f(x) for you, when they say "find f(3)", what they mean is that you need to define "f(x)" when x=3...
therefore in order to solve this problem, plug in "3" for "x" in "f(x)"
so...
f(3)=-(3)-4, which equals -7
The answer is -7. :D
