Given function is:

In order to find the rate of change, we have to find the value of function on x1 and x2
So,

The formula for finding the rate of change is:

Putting the values, we get

Hence,
Average rate of change for given function is: -2
Notice that in the expression n - 8,
the eight is the thing being subtracted.
We could read it like this: "Eight subtracted from a number."
So we can immediately see that the last option is not correct. It's the opposite of what we want. The third option is the same as the last, just worded differently: The number 8, decreased by a number n.
The second option is correct: A number n, but eight fewer than that.
n - 8
the correct answer is your third choice.
