1 Summer Assignment Wrm-up for Differentil Clculus Who should complete this pcket? Students who hve completed Functions or Honors Functions nd will be tking Differentil Clculus in the fll of 015. Due Dte: The first dy of school How mny of the problems should I do? ALL OF THEM How should I orgnize my work? You should show ll work in seprte sheets of looselef pper. If problem requires grph, then you should use grph pper. Keep your mterils in folder with 3-prongs. How will my techer know tht I ve done the work? Your techer will collect your notebook on the first dy of school. Your techer my choose to QUIZ or TEST you on this mteril if he or she feels it is necessry BE PREPARED! How well should I know this mteril when I return? You should recognize tht you ve seen this mteril before, nd you should lso be ble to nswer questions like the ones in this pcket. If the mteril is revisited in your next clss, it will only be for brief mount of time your techer will ssume tht ll you need is quick refresher. Note from your techers: We feel tht this summer work will truly help you succeed this yer. We understnd tht summer is time for relxtion nd fun, but it is impertive tht you spend some time before you return reviewing your mterils. This pcket is mndtory, nd you must tret it s you would ny other extremely importnt homework ssignment. You will be held ccountble for this mteril. We lso highly suggest tht you do bit of it t time in the weeks leding up to school don t leve it for the lst dy!!!

2 Wrm-up for Differentil Clculus Instructions: Complete the problems on loose-lef pper in pencil. If problem requires grph, plese use grph pper nd ruler. At the top of ech pge of your work, write your nme nd the pge number Complete ll the problems crefully. Show enough work to indicte your method of solution. Mke sure your work justifies your nswer. Keep the pcket nd your work in folder. Arrnge your work in pge order, nd plce the worksheets in report cover or 3-prong folder. Remember, your techer will collect your work on the first dy of school! Lte work will be severely penlized nd it my NOT be ccepted. Wht if I get stuck? - You should check out dditionl study mterils. Consult stndrd preclculus textbook. Find study buddy or clssmte to help you remember the mteril. Consult the following websites for hints nd exmples:

3 Wrm-up for Differentil Clculus pge 1 1. Grph f( x) ( x1) 4 using trnsformtions (shifting, stretching, reflecting, etc.) from the grph y x. Stte the trnsformtions needed.. For f( x) 3x 1x 4: i. Determine if the function hs mximum or minim nd explin how you know. ii. Algebriclly, determine the vertex of the grph. iii. Determine the xis of symmetry of the grph. iv. Algebriclly, determine the intercepts of the grph. v. Using the informtion in prts -d, grph the function by hnd. Plot dditionl points s needed in order to crete n ccurte grph. 3. Solve 3x x1 0 over the complex numbers. 4. Given the polynomil function Px ( ) ( x1) ( x ), do the following:. Find the x nd y intercepts of the grph. b. Determine whether the grph crosses or touches the x-xis t ech x-intercept. c. Describe the end behvior of the grph, tht is, describe wht hppens to the y-vlues s x increses. d. Using the informtion in prts -c, mke n ccurte sketch of the grph For the polynomil function g( x) x 5x 8x 15:. Determine the mximum number of rel zeros tht the function my hve. b. Given tht 3 is zero, determine the rel zeros of g. Fctor g(x) over the rel numbers. 6. Give the eqution of polynomil function with rel coefficients of degree 3 tht hs zeros of 5, 3 4i. 7. Sketch the grphs of these functions. Determine the mplitude, period, nd ny horizontl or verticl shifts. USE RADIANS. 1. y 43sin b. y 3cos 4

When using clcultor, round your nswer to three deciml plces.. x 5 15 c. 8 e x 4 b. log x 9 d. log x 3 log x 6 e. x3 x 7 f. x x log 4 log Given log nd log , find ech of the following:. log 6 b. log 3 c. log 3 d. log Use trnsformtions to grph ech function: identify the bse function, then describe ny shifts, stretches, etc. Sketch n ccurte grph of the function. Determine the domin nd give the eqution of ny symptotes.. f x x1 ( ) 4 b. g( x) 1log x A 50 mg smple of rdioctive substnce decys to 34 mg fter 30 dys.. How much of the substnce is left fter 10 dys? b. How long will it tke for there to be mg remining? 17. Find the inverse of f ( x). 3x 18. If the point (3,-5) is on the grph of the function gx, ( ) wht point must be on the grph of g 1 ( x), the inverse function?

6 Wrm-up for Differentil Clculus pge Ech of the following grphs psses through the point P (1, ). Mtch the correct function to ech grph. Identify chrcteristic tht enbles you to determine which grph.. y x b. y sin(30 x) 1 c. y log x d. e. 1 3 y x y x x 4 5 x 1 0. Find the domin of f( x), x 11x10 gx ( ) 1 nd g f ( x). x 1.
