gradarius Home Report an issue Help O Find the values of two points and average them Correct! The average rate of change is calculated by finding the slope of the secant line between two points. Find the average rate of change for the function f (x) = x + 2x near a = 2 over the interval [2,2 + h] for h = 0.1 , h =0.01 , and h =0.001 . f (2 +0.1) -f (2) 0.1 Now Rewrite so you can replace x in the formula for the function with 2.1 and 2. You should only have numbers left, no variables
