The question asks which input value produces the same output value for the two functions $f(x)$ and $g(x)$ shown on the graph. We need to find the point where both functions intersect, as that would represent the input where the output values for both functions are equal.

Analysis of the Graph:

• The red line represents $f(x)$, which appears to be a constant function at $y = 3$ (a horizontal line).
• The blue line represents $g(x)$, which is a line with a positive slope.

We are asked to determine where these two lines have the same output value, which occurs at the point of intersection.

By observing the graph:

• The two lines intersect at $x = 3$ with a common $y$-value of 3.

Conclusion:

The correct input value where the two functions have the same output is $x = 3$.
