Answer:
X=9
Y=13
Explanation:
Inputs are the X values in a function, while Outputs are the Y value.
The easiest way to solve this are to match points with the tables incontrast with the graph. For example Input 2 Output 1 translates the point (2,1). So if we have an Output of 8, we know that the Y point in the cordinate must be 8 (x,8 so far). Now we use the graph and see the x cordinate marked on the line for Y=8 we find that the X point must be 9. We apply the same thing for the second value in the table and derrive that the answer is 13 (14,13).
