(a) Give the second-order Taylor polynomial T2(x) for the function f(x)=x^1/2, centered at x=9.

(b) Use Taylor's Theorem to give the Error Term E2(x)= f(x)-T2(x), as a function of x and some z between 9 and x. (Note that here we are using z instead of which is used in the notes).

(c) Give an upper bound for the error E2(12).
