Muenzaniso weMibvunzo Inotaura Nezvekuchinja Kwebasa
Kuchinja-chinja kwebasa ipfungwa huru mumasvomhu, kunyanya mu algebra nekuongorora kwebasa. Kuchinja uku kunosanganisira mabasa akasiyana-siyana akadai sekushandura, kufungisisa, kuwedzera, uye kutenderera pagirafu yebasa. Kunzwisisa mashandiro anoita basa uye kukwanisa kurishandisa kumatambudziko hunyanzvi hunokosha, mune zvedzidzo uye mumashandisirwo ezuva nezuva.
Chinyorwa chino chichataura nezvemienzaniso yakati wandei yematambudziko ekushandura mashandiro, pamwe netsananguro, kuti tipe mufananidzo wakajeka wekuti tingashandisa sei pfungwa idzi. Tisati tapinda mumienzaniso iyi, ngationgororei mamwe marudzi akajairika ekushandura mashandiro:
1. Shanduro (Shift):
– Dudziro yakatwasuka: \( f(x) \longrightarrow f(x – h) \) apo \( h \) iri huwandu hwekuchinja kuenda kurudyi kana kuruboshwe.
– Dudziro yakatwasuka: \( f(x) \longrightarrow f(x) + k \) apo \( k \) iri huwandu hwekuchinjana kumusoro kana pasi.
2. Kufungisisa (Kufungisisa):
– Kufungisisa nezve \( x \) axis: \( f(x) \longrightarrow -f(x) \).
– Kufungisisa nezve \( y \) axis: \( f(x) \longrightarrow f(-x) \).
3. Kukura (Kuchinja muChikero):
– Kukura kwakatambanuka: \( f(x) \longrightarrow f(cx) \) apo \( c \) ndiyo horizontal scale factor.
– Kukura kwakamira: \( f(x) \longrightarrow af(x) \) apo \( a \) ndiyo vertical scale factor.
Nekunzwisisa uku kwekutanga, tichaenderera mberi kune mimwe mienzaniso yematambudziko ekuchinja mashandiro.
Muenzaniso Mubvunzo 1: Kushandura Kwakatsetseka
Mubvunzo: Uchitarisa basa \( f(x) = x^2 \). Sarudza chimiro chebasa mushure mekunge rashandurwa nemayuniti matatu kurudyi.
Kukurukurirana:
Shanduro yakataramuka inoshandura girafu yebasa iri pamwe chete ne axis ye \( x \ ). Shanduro iri kurudyi ine mayuniti matatu inoshandurwa se:
\[ f(x-3) \]
Saka, tinotsiva \( x \) imwe neimwe na \( x – 3 \) mubasa rekutanga:
\[ f(x-3) = (x-3)^2 \]
Saka basa rinoshandurwa kurudyi nemayuniti matatu nderinoti:
\[ (x-3)^2 \]
Muenzaniso Mubvunzo 2: Kushandura Kwakamira
Mubvunzo: Zvichienderana nebasa \( g(x) = \sqrt{x} \). Sarudza chimiro chebasa mushure mekunge rashandurwa nemayuniti mana kumusoro.
Kukurukurirana:
Shanduro yakatwasuka inoshandura girafu yebasa iri pamwe chete ne axis ye \( y \ ). Shanduro inokwidzwa kumusoro nemayuniti mana inoshandurwa se:
\[ g(x) + 4 \]
Saka, basa mushure mekududzirwa kumusoro nderekuti:
\[ \sqrt{x} + 4 \]
Muenzaniso Mubvunzo 3: Kufungisisa Nezve \( x \) Axis
Mubvunzo: Zvichienderana nebasa \( h(x) = \sin(x) \). Sarudza chimiro chebasa mushure mekunge raratidzwa pamusoro pe \( x \) axis.
Kukurukurirana:
Kufungisisa nezve \( x \) axis kunochinja chiratidzo chebasa. Saka tinowedzera basa ne -1:
\[ -h(x) \]
Saka, basa mushure mekufungisisa nezve \( x \) axis nderekuti:
\[ -\chivi(x) \]
Muenzaniso Mubvunzo 4: Kufungisisa Nezve \( y \) Axis
Mubvunzo: Zvichienderana nebasa \( j(x) = e^x \). Sarudza chimiro chebasa mushure mekunge raratidzwa pamusoro pe \( y \) axis.
Kukurukurirana:
Kufungisisa nezve \( y \) axis kunochinja chiratidzo che variable \( x \). Saka tinotsiva \( x \) yega yega ne \( -x \):
\[ j(-x) \]
Saka, basa mushure mekufungisisa nezve \( y \) axis nderekuti:
\[ e^{-x} \]
Muenzaniso Mubvunzo 5: Kupararira Kwakatwasuka
Mubvunzo: Zvichienderana nebasa \( f(x) = \cos(x) \). Sarudza chimiro chebasa kana kuwedzera kwakamira kwaitwa ne factor ye2.
Kukurukurirana:
Kuwedzerwa kwe vertical kunosanganisira kuwanza basa ne vertical scale factor. Saka tinowedzera basa ne 2:
\[ 2f(x) \]
Saka, basa mushure mekuwedzerwa kwe vertical ne 2 factor ndeiri:
\[ 2\cos(x) \]
Muenzaniso Mubvunzo 6: Musanganiswa weShanduro Dzakatambanuka neDzakatwasuka
Mubvunzo: Zvichienderana nebasa \( k(x) = \ln(x) \). Sarudza chimiro chebasa mushure mekunge rashandurwa mayuniti maviri kuruboshwe uye mayuniti matatu pasi.
Kukurukurirana:
Chekutanga, dudziro yemayuniti maviri kuruboshwe inoshandurwa se \( k(x+2) \). Chechipiri, dudziro yemayuniti matatu pasi inoshandurwa se:
\[ k(x+2) – 3 \]
Saka, basa rinotevera musanganiswa weshanduro iyi nderekuti:
\[ \ln(x+2) – 3 \]
Muenzaniso Mubvunzo 7: Musanganiswa weKufungisisa neKuwedzera
Mubvunzo: Zvichienderana nebasa \( m(x) = x^3 \). Sarudza chimiro chebasa mushure mekunge raratidzwa pamusoro pe \( y \) axis uye kuwedzera kwakamira kune factor ye1/2 kunoitwa.
Kukurukurirana:
Chekutanga, kufungisisa nezve \( y \) axis kunoshandurwa se \( m(-x) \). Chechipiri, kuwedzera kwe vertical ne factor ye 1/2 kunoshandurwa se:
\[ \frac{1}{2} m(-x) \]
Saka, basa rinotevera musanganiswa uyu wekufungisisa nekuwedzera nderinotevera:
\[ \frac{1}{2}(-x)^3 = -\frac{1}{2} x^3 \]
Muenzaniso Mubvunzo 8: Kukura Kwakatsetseka
Mubvunzo: Zvichienderana nebasa \( n(x) = \tan(x) \). Sarudza chimiro chebasa kana kuwedzera kwakatarwa kwaitwa ne factor ye3.
Kukurukurirana:
Kukura kwakatambanuka kunosanganisira kuwanza variable \( x \) ne 1/c (apo \( c \) iri horizontal scale factor). Saka tinowanza variable \( x \) ne 1/3:
\[ n(\frac{x}{3}) \]
Saka, basa mushure mekuwedzerwa kwe tarakita ne 3 ndiro:
\[ \tan(\frac{x}{3}) \]
