2 Let x} 2 f 60(t2 3t + 2)::"2 dt. Find all intervals on which f is increasing. If you nd more than one, present a comma-separated list of intervals. 1 Answer: ::: (Here are the official notes on interval notation in WeBWorK.) Background: A generic function h is called Increasing on the interval I exactly when the inequality h(a:1) 0 for each m in some open interval (a, b) and h is continuous on the closed interval [(1, b], then It is increasing on [(1,3)]
