A function f and value a are given below. Approximate the limit of the difference quotient, 1 f(x) = a = 6 x+5' lim h0 f(a+h) f(a) - h using h = 0.1, 0.01. (Round your answer to within three decimal places if necessary, but do not round until your final computation.) a. When h = 0.1, f(a + h) - f(a) h b. When h = -0.1, f(a + h) - f(a) h c. When h = 0.01, d. When h = -0.01, f(a+h) f(a) h f(a+h) - f(a) h = GI
