L Let Mm) = $31n(1 3x). (a) Use the series for 1n(1 + cc) expanded at :r = O to obtain a Taylor series for h. (b) Explain why your work in (a) shows that h has a critical point at a: = 0. (c) Use the series found in (a) to classify the critical point. ) d Suppose instead we attempted to use the second derivative test to classif the critical Y point. Without doing the calculation, what would have been the result of the test
