When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h)2 Therefore, the slope of the secant line between any two points on this function is 2x + h
Average rate of change is a ratio of change on Y-axis to change on X-axis ([tex]\frac{change \ in \ Y}{change \ in \ X} \Rightarrow[/tex] [tex]\frac{f(3)-f(0)}{3-0}=\frac{7-1}{3}=2[/tex].
