I: (25 points, no partial credit) a) For some function f ( x ) you know that | f (2 + h ) - f (2) | ≤ 7 | h | 3 . Find δ > 0 so that | f (2 + h ) - f (2) | < ε whenver | h | < δ . b) True or false 0 < a < 1 a > a 0 < a < 1 a 2 < a c) Find all x for which x 2 + 3 x + 2 > 0 d) Find the linear function ( x ) whose slope is - 2 and has the point (1 , 2) on its graph. e) Find the linear function ( x ) that has the points (1 , 2) and (2 , 3) on its graph.
