What is the range of y = 5x -2 if the domain is {-3, -1, 0, 1, 3}? Answer {-13, -3, 2, 3, 13} {12, 3, 0, 3, 13} {-17, -7, -2, 3, 13}
Plug all the values of the domain in for x. The answers you get will be the range.
Im sorry. What is the answer?
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?
