Question

Which input value produces the same output value for the two functions on the graph? A. x = –3 B. x = –1 C. x = 1 D. x = 3

Answer 1

D. x = 3.

Explanation:

That would be the x value correspond to the point of intersection of the 2 graphs. That is x = 3.

To confirm this, plug x = 3 into each function and you'll see the output to be -1 in each case.

Answer 2

D. x = 3

Explanation:

When x = 3 on both graphs, y is equal to -1 on both graphs.

We can also see that there is the same output value because there is an intersection point at x = 3.
