Consider the following function. f(x) = x2 + 5x − 6 Find the average rate of change of the function over the interval [0, 1]. Change in y/change in x = Compare this rate with the instantaneous rates of change at the endpoints of the interval. f'(0) = f '(1) = Find the marginal cost for producing x units. (The cost is measured in dollars.) C = 455 + 6.75x2/3 dC/dx = dollars per unit

Question: Let f(x) be a function satisfying f(0) = 0, f'(0) = 5, f'(0) = -6 and |f(3)(x) = 6 for 0 5x51. Find the Taylor polynomial of degree 2 off at x = 0 and then find lim 5x-f(x) x2 x=0+ Answer: The Taylor polynomial of degree 2 off at x = 0 is P2(x) = Near x = 0, the function f(x) is equal to P2(x) plus some remainder, that is f(x) = P2(x) + R3(x).
