Chapter 2, Problem 47(choose chapter or problem)
Graph the functionf(x) = x4 - 3x3 - 6x2 + 7x + 30
in the viewing rectangle [-3, 5] by [-10, 50].
Using the graph in part (a) to estimate slopes, make a rough sketch, by hand, of the graph of f’. (See Example 2.8.1.)Calculate f’(x) and use this expression to graph f’. Compare with your sketch in part (b).
