Which input value produces the same output value for the
two functions on the graph?
x=-1
x=0
x=3
x=4

x = 4

Step-by-step explanation:

The 2 graphs have the same output, y = 3 at the point of intersection

This occurs when the input is x = 4

Option D.

Step-by-step explanation:

The given graph shows the two functions.

Red line represents the function f(x). From the given we conclude that

Blue line represents the function g(x). From the given we conclude that

Since f(4)=g(4)=3, therefore at x=4 the function have same output values.

Thus, the correct option is D.
