Let f(x)=−x√3 . what is the average rate of change of f(x) from 8 to 64?
−1/28
1/28
−28
28

Step-by-step explanation:

The given function is

The average rate of change of this function is the slope of the secant line connecting the points (64,f(64)) and (8,f(8));

We substitute the functional values into this function to obtain;

This simplifies to;
