I: (25 points, No partial credit) a) For some function f ( x ) you know that | f (1 + h ) - f (1) | ≤ 5 | h | 2 . Find δ > 0 so that | f (1 + h ) - f (1) | < ε whenver | h | < δ . b) True or false a < b a 2 < b 2 0 < a < b a < b c) Find all x for which x 2 + x - 2 > 0 d) Find the linear function ( x ) whose slope is 2 and has the point (2 , 1) on its graph. e) Find the linear function ( x ) that has the points (2 , 1) and (3 , 2) on its graph.
