In this problem we will first find an estimate to 1.5 using a Taylor polynomial P2(1.5) and then use the Remainder Estimation Theorem to approximate 1.5 - P2(1.5). This problem has parts (a)-(g). (a) What should f(x) and the center a be in order to compute a Taylor polynomial P,(x) at x= a? The function is f(x) = and the center is a = (b) Find the Taylor polynomial of order 2, i.e., P,(x), generated by the f(x) is part (a) at the center x= a from part (a). P2(x) = (c) Use P2(x) from part (b) to find an approximation to V1.5. (Your answer can be written as a sum of fractions.) 1.5 = (d) Compute f (3)(x) and f (4) (x). f(3) (x) =| and f(4(x) = (e) Which of the following is true? O A. f(t) < 0 and f (4) (t) < 0 for asts 1.5, so f ((x) is a negative, decreasing function on the interval [a, 1.5). O B. f(3) (t) > 0 and f (4) (t) < 0 for asts1.5, so f ((x) is a positive, decreasing function on the interval [a, 1.5]. O C. f(3) (t) > 0 and f(4) (t) > 0 for asts1.5, so f ((x) is a positive, increasing function on the interval [a, 1.5]. O D. f(3) (t) < 0 and f(4) (t) > 0 for asts 1.5, so f (3(x) is a negative, increasing function on the interval [a, 1.5). (f) Find smallest number M>0 that satisfies f (t) sM for all asts 1.5. M = since f(3) (t) will have an absolute maximum at t= in the interval [a, 1.5). (g) Fill in the blank. Using the value for M from part (f), the Remainder Estimation Theorem says that |1.5 - P,(1.5)| |R,(1.5)| 0.
