Exercise 1. Find the Taylor polynomial of order 3 for the functiong(x) =9 + x. (Hint: The coefficients are rational, and some have very large denomi-
nators.)
Exercise 2. Consider the function f(x) = 2x3 + 7x2 9x 11.
(A) Find the order 3 Taylor polynomial for f(x) centered at x = 0.
(B) Find the order 3 Taylor polynomial for f(x) centered at x = 1. (Hint:If you do this correctly, this polynomial equals f(x), although it has adifferent format.
Exercise 3. Suppose that g(x) is a function such that g(0) = 8, g(0) = 5,g(0) = 5, g(0) = 16, g4(0) = 44 and g5(0) = 44.
(A) Find the order 5 Taylor polynomial for g(x) centered at x = 0.
(B) Find the order 4 Taylor polynomial for h(x) = g(x) centered at x = 0.
Exercise 4. Suppose that the order 5 Taylor polynomial, centered at 0, for afunction F (x) is
