1. Consider the function /(r) = r- (a) Find the e- and y intercepts. (b) Find the critical numbers. (c) Find the intervals on which f is increasing and the intervals on which f is do- (d) Find the relative extrema of f. Open with (c) Find the intervals on which f is concave up and the intervals on which f is concave down. (f) Use all of the above information to sketch the graph of f. 2. Calculate Ar - 2r + 1 Jim
