Graphical Polynomials

Question

What is the rate of change between x=0 and x=5?

Answer 1

Let P(x) be the polynomial. The rate of change on any interval is equal to the slope of the secant line connecting the two endpoints of the interval:

Rate of Change = (P(5)-P(0)) / (5-0)

You did not provide the polynomial function P(x), but you can compute the values of P(5) and P(0) for yourself (or read them from the graph, if provided).
