1. Compute the following integrals. (a) 5 Z x x x + 1 dx 1 / 2 dx , so x dx = 2 (b) 5
2. Consider the function f ( x ) = e 1 /x . (a) 1 Is f even, odd or neither?
(b) 8 Find all local extrema, points of inflection, and horizontal and vertical asymptotes of the graph of f .

so f 00 ( x ) vanishes at x = - 1 / 2, is negative for x < - 1 / 2 and positive otherwise. There is a point of inflection at x = - 1 / 2.
