    • 4.1: Ufafanuzi wa Kazi
      Kazi ni sheria ambayo inateua kila kipengele katika seti ya maadili ya pembejeo (uwanja), kipengele kimoja na kimoja tu katika seti ya maadili ya pato (upeo).
    • 4.2: Uthibitishaji wa Kazi
      Kazi zimeandikwa kama” f (x) = kujieleza algebraic”. Tangu y = f (x), f (x) ni kitu kimoja kama y. nukuu hii inaonyesha x kama pembejeo katika kazi, na f (x) kama pato kutoka kazi.
    • 4.3: Kutathmini Kazi
      Wakati kazi ni tathmini, kuchukua nafasi ya x na kupewa thamani numeric au kujieleza algebraic, na kisha kurahisisha matokeo.
    • 4.4: Kazi za mstari
      Kazi ya Linear ni kazi ambayo ina fomu f (x) =mx+b. Mstari wowote ambao unaweza kuonyeshwa kwa fomu y=mx+b pia ni kazi.
    • 4.5: Kazi kamili ya Thamani
      Ili kuunda kazi za thamani kamili, chagua maadili madogo ya x, na uhesabu thamani ya f (x) kutoka kwa kazi iliyotolewa ili kuunda jozi zilizoamriwa. Tatu zilizoamriwa jozi ni kiasi cha chini kinachohitajika ili graph kazi ya thamani kamili.
    • 4.6: Kazi nyingi
      Kazi ya Polynomial ni kazi ambayo inaweza kuandikwa kwa fomu ya jumla.
    • 4.7: Domain na Aina ya Kazi
      Domain ya kazi ni maadili yote iwezekanavyo ya x ambayo inaweza kutumika kama pembejeo kwa kazi, ambayo itasababisha idadi halisi kama pato. Aina ya kazi ni seti ya maadili yote ya pato iwezekanavyo ya kazi.
    • 4.8: Kazi za kuchora (bila kutumia Calculus)
      Kuna baadhi ya kazi za msingi, aitwaye kazi toolkit, kwamba wanafunzi wanapaswa kutambua kwa ufafanuzi wao kazi na grafu yao. Kwa kila moja ya kazi hizi, x ni variable pembejeo, na f (x) ni variable pato.
    • 4.9: Utungaji wa Kazi
      Nukuu f (g (x)) na g (f (x)) inaweza kuwa rahisi kuelewa kuliko kutumia operator wa utungaji. Kwa f (g (x)), fikiria kuifunga mfuko. Zawadi huwekwa ndani ya sanduku (zawadi ni g (x), sanduku ni f (x)) na sasa iliyotiwa, f (x), ina zawadi g (x).
    • 4.10: Kupata Mizizi yote ya Real ya Kazi
      Ili kupata mizizi halisi ya kazi, tafuta ambapo kazi inakabiliana na x-axis. Ili kupata ambapo kazi inakabiliana na x-axis, weka f (x) =0 na kutatua equation kwa x.
    • 4.11: Kazi ya Ufafanuzi wa Kipande
      Kazi zilizoelezwa kwa kipande ni kazi ambazo hufafanuliwa kwa kutumia milinganyo tofauti kwa sehemu tofauti za kikoa.
    • 4.12: Mifano ya Matumizi ya Kazi
      Mifano iliyowekwa ya kazi (matatizo ya neno la AKA!) inaweza kuchukua aina nyingi.
