SUMMARY

The discussion focuses on finding the vertical asymptotes of the function f(x) = 1/(1 + ln|x|). It establishes that vertical asymptotes occur at x = 1/e and x = -1/e, where the function is undefined. The limits approaching these points from both sides confirm the behavior of the function near the asymptotes. The discussion emphasizes the importance of understanding the properties of the natural logarithm function in determining the asymptotic behavior.

PREREQUISITES
  • Understanding of limits in calculus
  • Familiarity with the natural logarithm function (ln)
  • Knowledge of vertical asymptotes in rational functions
  • Basic algebraic manipulation skills
NEXT STEPS
  • Study the properties of the natural logarithm function and its graph
  • Learn how to calculate limits approaching vertical asymptotes
  • Explore the concept of asymptotic behavior in rational functions
  • Practice finding vertical asymptotes in various rational functions
USEFUL FOR

Students studying calculus, mathematics educators, and anyone interested in understanding the behavior of functions near vertical asymptotes.

[tex] f(x)=\frac{1}{1+ln|x|}\\[/tex]
[tex] x\neq \frac{1}{e}\\[/tex]
[tex] x\neq \frac{-1}{e}\\[/tex]
[tex] lim_{x->\frac{1}{e}^+}\frac{1}{1+ln|x|}=\\[/tex]
[tex] lim_{x->\frac{1}{e}^-}\frac{1}{1+ln|x|}=\\[/tex]
i can't immagine ithe values in this function

First, 1/e is a positive number so you can just drop the absolute value.

Second, ln e-1= -1. Since ln(x) is an increasing function, if x< e-1, ln(x)< -1 and if x> e-1, ln(x)> -1. That's all you need.
