Ntsiab Lus

  1. Thaum graphed, lub logarithmic muaj nuj nqi zoo ib yam li cov square cag muaj nuj nqi , tab sis nrog ntsug asymptote raws li x mus txog 0 ntawm sab xis.
  2. Lub ntsiab lus (1, 0) yog nyob ntawm daim duab ntawm txhua tus logarithmic kev ua haujlwm ntawm daim ntawv y = logbx y = l o g b x, qhov twg b yog tus lej tiag tiag.

Tsis tas li ntawd, koj yuav pom qhov sib npaug ntawm kab rov tav asymptote li cas?

Txhawm rau nrhiav kab rov tav asymptotes:

  1. Yog hais tias qhov degree (qhov loj tshaj plaws exponent) ntawm tus denominator loj dua qhov degree ntawm tus lej, kab rov tav asymptote yog x-axis (y = 0).
  2. Yog hais tias lub degree ntawm tus zauv loj dua tus denominator, tsis muaj kab rov tav asymptote.

Tom qab, lo lus nug yog, dab tsi yog cov cuab yeej ntawm lub cav? Logarithm ntawm ib yam khoom Nco ntsoov tias lub khoom ntawm exponents thiab logarithms zoo sib xws heev. Nrog exponents, kom muab ob tug lej nrog tib lub hauv paus, koj ntxiv cov exponents. Nrog logarithms , lub logarithm ntawm cov khoom yog qhov sib npaug ntawm cov logarithms.

Ua li no, koj yuav pom cov asymptotes ntawm LN daim duab li cas?

Nrhiav qhov ntsug asymptote ntawm daim duab ntawm f(x) = ln (2 x + 8). Kev daws. Txij li thaum f yog logarithmic muaj nuj nqi, nws daim duab yuav muaj ntsug asymptote qhov twg nws qhov kev sib cav, 2x + 8, yog sib npaug rau xoom: 2x + 8 = 0 2x = −8 x = −4 Yog li, daim duab yuav muaj ntsug asymptote x = -4.

Koj pom cov asymptotes ntawm kev ua haujlwm li cas?

Nrhiav Kab rov tav Asymptotes ntawm Rational Functions

  1. Yog tias ob qho tib si polynomials yog tib qib, faib cov coefficients ntawm cov ntsiab lus siab tshaj plaws.
  2. Yog hais tias lub polynomial nyob rau hauv tus lej yog qis dua tus denominator, x-axis (y = 0) yog kab rov tav asymptote.
