Do the following for the function f(x) = 10x2+ 5x. (a) Express the slope of the secant line in terms of x and h. (b) Find msoc for h = 0.5, 0.1, and 0.01 at x = 1. What value does mccr 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 viewina window. (a) Type the slope of the secant line in terms of x and h. msec = (Simplify your answer. Do not factor.) (b) For h= 0.5 at x = 1, msec = (Round to two decimal places as needed.) For h = 0.1 at x = 1, msec = (Round to two decimal places as needed.) For h = 0.01 at x = 1, msec = (Round to two decimal places as needed.) As h approaches 0, msec approaches (Type an integer or a decimal.) (c) The equation for the secant line at x = 1 with h = 0.01 is y= (Type the expression in slope-intercept form. Round coefficients to two decimal places as needed.) (d) Which of the following is the graph of f and the secant line? O C. O B. O A. LLLLLLLLL
