Question

How can I determine the rate of change in a relationship and how do I explain what it means in terms

Answer 1

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.
