Question

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}

Answer 1

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

Answer 2

Im sorry. What is the answer?

Answer 3

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

Answer 4

Its B?

Answer 5

?

Answer 6

or is it A?

Answer 7

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

Answer 8

I have no idea.

Answer 9

What is 5 times -3?

Answer 10

-30

Answer 11

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?

Answer 12

15?

Answer 13

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.

Answer 14

-13!

Answer 15

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?
