    f(-3) is simply x = -3. Knowing this, we can plug in -3 with the equation f(-3) = -2(-3) -3

    Not quite. Let's focus on -2(-3). When we have a equation like this, we have to multiply -2 and -3. So what is -2 x -3 =?

    No your not :) you are doing good. Breaking the problem down always helps me! So the answer is f(-3) = 3!
