Chapter 3, Problem 86

(choose chapter or problem)

8188 require the following discussion of a secant line. The slope of the secant line containing the two points and on the graph of a function may be given as In calculus, this expression is called the difference quotient of (a) Express the slope of the secant line of each function in terms of x and h. Be sure to simplify your answer. (b) Find for 0.1, and 0.01 at What value does approach as h approaches 0? (c) Find the equation for the secant line at with (d) Use a graphing utility to graph and the secant line found in part (c) on the same viewing window. f1x2 = -x2
