So firstly, we have to find f(x) when x = 8 and x = 0. Plug the two numbers into the x variable of the function to solve for their f(x):
Now that we have their y's, we can use the slope, aka average rate of change, formula, which is . Using what we have, we can solve it as such:
In short, the average rate of change from x = 0 to x = 8 is 5/21.
