Answer C and D

Of a) Graph the function f(x) = x + 6x. b) Draw the tangent lines to the graph at the points whose x-coordinates are - 6, - 3, and 0. f ( x + h) - f(x) c) Find f'(x) by determining lim h -+ 0 h d) Find f'( - 6), f'(-3), and f'(0). These slopes should match those of the lines in part (b). . . . X Library ces b) Choose the correct tangent lines to the graph. O A. O B. O C. D Ay + Ay ools c) f'(x) =
