Do t forget out the 3-step proess to prove tht prtiulr -vlue ( ) is isotiuity. ). ƒ() eists ). lim ƒ() eist (Rememer to hek the left right-h limits) 3) lim ƒ() ƒ() 3. Evlute limits tht pproh ifiity (horizotl symptotes): lim f() L 4. Give prtiulr futio fi the equtio of the tget lie y y m(- ) t give poit P(, f()). 5. Give positio futio, s(t), e le to lulte the veloity of prtile t t 6. Re grph stte where the futio is NOT DIFFERENTIABLE why. Sie the erivtive is limit, the erivtive eists t poit oly if it (the slope of the tget) eists from the left from the right AND these two vlues equl eh other! Chpter 3.

3 Me Vlue Theorem: If ƒ is futio tht stisfies the followig hypothesis:. ƒ is otiuous o the lose itervl [, ].. ƒ is ifferetile o the ope itervl (, ). The there is umer i (, ) suh tht ƒ() - ƒ() ƒ () or equivletly ƒ() - ƒ() ƒ ()[( )] - 3. Setio 4.3: How Derivtives Affet Grph Give ƒ() you shoul e le to: i). Fi the itervls o whih ƒ is iresig or eresig You o this y uilig tle usig the ID Test. ii). Fi the lol m lol mi vlues of ƒ. You o this y reig the sig hges i the tle you uil for step i). This is the st Derivtive Test. iii). Fi the poits of ifletio itervls of ovity. You o this y tkig the seo erivtive evlutig where ƒ () 0 or D.N.E. These re possile poits of ifletio. You the uil other tle re the sigs of ƒ (). This will lso vlite y possile POIs. 4. Setio 4.4: L Hospitl s Rule 0 Oly works for limits tht re ietermite : ± 0 C e use multiple times if the ew limit stisfies the ove step! 5. Setio 4.7: Optimiztio Prolems Chpter 5:. 5.
