Homework 20

Section 11-3: 34, 38, 42

Section 11-4: 36, 40, 44

Section 12-1: 10, 12, 14, 16, 18, 20, 24, 28; Application 98

For problems 20, 24, and 28 in section 12-1, generate a sign chart for the
derivative to indicate when the function is increasing and decreasing. For
each local extremum, give the x-coordinate at which the extremum occurs, the
value of the function for that x-value, and
whether that value is a local maximum or a local minimum.
