Limit of the function ((1+x)/(1+2*x))^x

You have entered [src]

              x
     / 1 + x \ 
 lim |-------| 
x->oo\1 + 2*x/

\lim_{x \to \infty} \left(\frac{x + 1}{2 x + 1}\right)^{x}

Limit(((1 + x)/(1 + 2*x))^x, x, oo, dir='-')

Lopital's rule

There is no sense to apply Lopital's rule to this function since there is no indeterminateness of 0/0 or oo/oo type

\lim_{x \to \infty} \left(\frac{x + 1}{2 x + 1}\right)^{x} = 0

\lim_{x \to 0^-} \left(\frac{x + 1}{2 x + 1}\right)^{x} = 1

\lim_{x \to 0^+} \left(\frac{x + 1}{2 x + 1}\right)^{x} = 1

\lim_{x \to 1^-} \left(\frac{x + 1}{2 x + 1}\right)^{x} = \frac{2}{3}

\lim_{x \to 1^+} \left(\frac{x + 1}{2 x + 1}\right)^{x} = \frac{2}{3}

\lim_{x \to -\infty} \left(\frac{x + 1}{2 x + 1}\right)^{x} = \infty
