Neil took 3 math tests this year. The number of hours he spent studying for each test and the corresponding grades he earned are shown in the table. Is the relation of hours of study time to grade earned on a tae a function? Explain why. Use the graph to justify your answer.

No, it is not a function

Step-by-step explanation:

A function can be seen on a graph when each X variable only corresponds to one Y variable. On this graph, the hours spent studying is your X, and when we look at the chart, we can see that there are 2 times he spent 6 hours studying, but they have 2 different grades. Let it be known that the same Y variable CAN correspond to more than one X variable, but not the other way around.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

x = 3 ± √(5+y)
