Question

If (-3, y) lies on the graph of y = 3-x, then y =
1/27
-27
27

Answer 1

Hello, the correct answer is, 27

Explanation:

Substitute -3 into -x

We know that since they are both negatives, they cancel out. Therefore, you substitute 3 into y = 3^-x.

y = 3^3

y = 27

Answer 2

y = 6

Explanation:

[] We can plug in our x value of -3, from the coordinate point, and solve for y.

y = 3 - x

y = 3 - (-3)

y = 3 + 3

y = 6

[] We can also graph the equation, and find the point where x = -3

I do not see this option in the answers you have provided, so either I miss interpreted something, or something else got messed up.
