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 test a function? Example why. Use the graph to justify your answer.
In order to determine if the relation of hours of study time to grade earned on a test is a function, we need to verify if there is a unique grade for each amount of study time.
From the table, we can see that Neil spent different amounts of time studying for each test: 4 hours for the first test, 6 hours for the second test, and 8 hours for the third test.
For the first test, Neil received a grade of 85. However, there is no grade corresponding to 4 hours of study time in the second and third tests. This means that 4 hours of study time does not have a unique grade, and violates the definition of a function.
Therefore, the relation of hours of study time to grade earned on a test is not a function.
Please note that you mentioned there is a graph to justify the answer, but it is not provided. Hence, we are solely basing our answer on the given information in the table.
