For the function f(x)=10x^2+8x
a.] express the slope of the secant line in terms of x and h.
b.] find m subscript secant for h=0.5, 0.1, and 0.01 at x=1. what value does m subscript secant approach as h approaches 0?
c.] find the equation for the secant line at x=1 with h=0.01.
d.] graph f and the secant line found in part (c) on the same viewing window.
