The graph of a function f is given. Use the graph to estimate the following. (Enter your answers using interval notation.) The x y-coordinate plane is given. The curve begins at the point (3, 0), goes down and right linearly, sharply changes direction at the point (2, 1), goes up and right linearly, sharply changes direction at the point (1, 4), goes down and right linearly, sharply changes direction at the point (0, 4), goes up and right linearly, sharply changes direction at the point (4, 1), goes down and right linearly, and stops at the point (5, 3). (a) The domain and range of f. domain range (b) The intervals on which f is increasing and on which f is decreasing. increasing decreasing
