In each part, sketch the graph of a continuous function f with the stated properties on the interval − ∞ , + ∞ . (a) f has no relative extrema or absolute extrema. (b) f has an absolute minimum at x = 0 but no absolute maximum. (c) f has an absolute maximum at x = − 5 and an absolute minimum at x = 5 .
