The complete question is:
Which expression below gives the average rate of change of the function g(x)= -x^2 - 4x on the interval 6 < x < 8
When we have a function f(x), the average rate of change of this function in the interval a < x < b is given by:

Then if we have the function g(x) = -x^2 - 4x
and we want to find the average rate of change in the interval 6 < x < 8 we need to compute:
