Answer:
D.

Explanation:
We have been graph of two functions on coordinate plane. We are asked to find the input value that produces the same output value for the two functions.
To find the input value that produces the same output value for the two functions, we need to find x-value for which both functions has same y-value.
Upon looking at our given graph, we can see that at
, the value of both functions is
.
Therefore, our required input value is
and option D is the correct choice.
