Answer:
x = 3 renders the same output for both functions
Explanation:
From the graph, we see that at the point x = 3 both lines intersect. This means that their y value coincide for that value of x.
We check using the functions' expressions to verify that our answer is correct. Then we evaluate both functions separately at x = 3:

So we conclude that effectively, the input x=3 produces equal output value (-1) for the two given functions.
