Part b asks: "On what time interval(s) is the bug speeding up. Explain your reasoning." How do I solve this problem?

A bug begins to crawl up a vertical wire at time t = 0. The velocity and acceleration of the bug at time t for 0 s t s 10 is given by the functions whose graphs are shown below. (t) a(t) 3 2 (a) (2 points) On what time interval(s) is the bug moving to the left? Explain your reasoning. (b) (4 points) On what time interval(s) is the bug speeding up? Explain your
