time. If one travels north at 60 miles per hour and the other
travels east at 45 miles per hour, how fast will the distance
between them be changing after 3 hours?
2. Find the critical values of , find the intervals on which
f(x)is increasing and decreasing, and any local maximum or
minimum values.
Critical values?
Increasing on?
