the table shows the relationship between the average number of hours students study for a mathematical test and their average grade

The correct option is D) Non-linear function that increases then decreases.

Step-by-step explanation:

Consider the provided table.

If the differences between the y values remains constant then the equation is linear and has a constant slope.

Now find the difference between the y values as shown:

78 - 62 = 16

85 - 78 = 7

Since, the difference of y value is not same. So, the function is nonlinear function.

Now observe the y values:

62, 78, 85 74

Here, we can observe that the y value increases then decreases.

Thus, the correct option is D) Non-linear function that increases then decreases.
