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.
