please answer (a) thank you!

MY NOTES Consider the following function. f(x) = In(1 + 2x), a = 3, n = 3, 2.8 5 x s 3.2 (a) Approximate f by a Taylor polynomial with degree n at the number a. T3(X) = X (b) Use Taylor's Inequality to estimate the accuracy of the approximation f(x) = T,(x) when x lies in the given interval. (Round your answer to six decimal places.)
