Plug all the values of the domain in for x. The answers you get will be the range.

I explicitly told you how to find the answer. It doesn't get any easier than that.

When you plug 3 into the equation for x, what number do you get for y?

Incorrect. Let's just do 5 times 3. One of your hands has 5 fingers, right? How many fingers would you have if you had 3 hands?

Yes. But since we're multiplying 5 times negative 3, we put a negative sign in front of the answer. So 5 times 3 = 15. In the original equation, it says y = 5x  2. So now you need to solve: 15 minus 2.

Actually, since we're subtracting from a negative number, the answer will be "more negative." Another way to think of it is (15+2). So you would solve for 15+2, and then put a negative sign in front of it. What do you get?
