Question

A. Input 3, output 0B. Input 4, output 5C. Input -3, output 0D. Input 2, output 3

Answer 1

The only valid pair is B.

To determine this we need to remember that the input is the value of x and the output is the value of y.

For the input 4, that is x=4, the graph passes through the output is 5, that is y=5. This means that the graph passes through the point (4,5).
