Help us to give to others in ways that meet their deepest needs. We await your coming with gratitude. Amen.Here is the link to the Holt online graphing calculator: Brain break = jump square p.12 PAPER TOSS TURN IN HW while listening to our prayer song BE SURE TO TURN IN GLOG AND ERP GLOG WITH YOUR HW!!Homework was: HW = do corrections for any wrong from THE ENTIRE PACKET = CORRECTIONS NEED TO BE ON NEW NBPAPER NOT ON TOP OF ORIGINAL WORK – YOU SHOULD HAVE BEEN DOING CORRECTIONS EACH NIGHT SO – TONIGHT YOU SHOULD SHOULD ONLY HAVE TO DO CORR FOR 38-42 SKIP 39… saw AND/OR explain … ON NOTEBOOK PAPER … do a good job!! TODAY = QUESTIONS!1.==>ENDHW Questions?? Prepare to do a problem at the board: +5 to your hw grade Today = ERP = EXAM REVIEW PACKET # 8-14You must:1. work on notebook paper not from a spiral2. wtp = write the problem3. saw to find the answer – look in (1) book --- look in index/glossary to find out which lesson to look at!! If no work then explain!!and (2) HW for help!! 4. write the answer you choose and the letter of that answer5. skip a line6. do 1-5 again…and again…and again…ANSWERS TO 22-28 22.skip 23.-524.graph…25.a.5, 25, 125, 62526.solve for x x = ± 227.graph – then you can see the answer = about 1.5 sec28.FOIL x = 3/5 ; x = -4/5 ACTIV BOARD FILE for work - on weebly!Let’s make the file – everybody gets to do one 23=tat24=mic=board25=will26=harr=board27=trav28=kat=boardHints for HW – SAW!!29.use quadratic formula x = 3 ± √230.square root both sides x = (-3 ± 5) / 331.use quadratic formula x = (5 ± √33) / 432.I = Prt t = about 1.2333.skip34.skip35.solve for x then graph on number line…then write in interval notation…35.[-12, ∞)36.skip37.what can the discriminant NOT be??It cannot be < 0 … So set discriminant < 0 … What you get – it cannot be…So if x cannot be < -4 then what can it be??37.the domain is x ≥ -4HW ANSWERS – THESE WERE IN THE FILE LAST NIGHT!38.you try!! 4 parts c.domain:-5 ≤ x < 4 d.range: -5 ≤ y ≤ 5 39.skip40.parent is … ???41.do f(x) – g(x) … CLT … clean up … simplify …Then what can the domain be…?any restrictions? No …42…………………………….38a.-2 = mic38b.5 = will40.parent f(x) = x2 quadratic 41.-x2 + x + 6 domain: all Real #s42.a.8 ft/secb.14 ft/secright37487PRECALCULUS HOMEWORK:0PRECALCULUS HOMEWORK:Never give up! Never surrender! ~ Galaxy Quest!HW = STUDY = do corrections for any wrong from THE ENTIRE PACKET = CORRECTIONS NEED TO BE ON NEW NBPAPER NOT ON TOP OF ORIGINAL WORK – YOU SHOULD HAVE BEEN DOING CORRECTIONS EACH NIGHT SO – TONIGHT YOU SHOULD SHOULD ONLY HAVE TO DO CORR FOR 38-42 SKIP 39… saw AND/OR explain … ON NOTEBOOK PAPER … do a good job!! Look up and cite example for any you don’t know how to do from memory!!!...ie…either you know how to do it by heart from memory – or – you cite the example you found to help you…AND START OTHER CORRECTIONS FOR ALLto use online graphing to graph any you need to!Try these: ................
