For the function given below, answer (a) through (c).
(a) For each function below, find the average rate of change
of f from 1 to x:
[f(x) - f(1)]/(x - 1), where x cannot = 0.
(b) Use the result from part (a) to compute the average rate of change from x = 1 to x = 2. Be sure to simplify.
(c) Find an equation of the secant line containing the points
(1, f(1)) and (2, f(2)).
HERE IS THE FUNCTION:
f(x) = x^3 + x
