Which point is on the graph of the function shown below

Answer:
B. (0,3)
Step-by-step explanation:
Let's remember that in an ordered pair, the first number represents the x-coordinate and the second one represents the y-coordinate.
To know if an ordered pair (or point) is on the graph of a function, we just need to look the first number of the pair and check that the y-coordinate that it has on the graph matches the second number of the pair.
Let's take for example the point A.(4,-4).
When we look it on the graph, the x-coordinate 4 corresponds to the y-coordinate -5. That doesn't match with the point we had, therefore (4,-4) is not on the graph of the function.
If we repeat this with each point, we'll see that the only point that is on the graph is B.(0,3).
