critical point: f'(c)=0 or DNE
incr/decr:
1) find crit pts of f
2) make sign chart for f'
3) plug in values to determine if incr or decr
find abs max/min of f on [a,b]
1) evaluate f @ x = a,b (endpoints)
2) find crit pts on [a,b] (set der=0) & evaluate f @ crit pts
3) compare values (largest=abs max; smallest=abs min
concavity:
1) f''(x)
2) sign chart for f''
3) test for concavity
4) inflection pt = where concavity switches optimization
1) draw diagram & introduce variables
2) write down conditions on the
variables
3) determine the quantity to be
maximized/minimized
4) write down an equation for the
quantity to max/min & reduce # of
variables
5) use der to find max/min value
