Step 1.2
Since as from the left and as from the right, then is a vertical asymptote.
Step 1.3
Evaluate to find the horizontal asymptote.
Step 1.3.1
Apply L'Hospital's rule.
Step 1.3.1.1
Evaluate the limit of the numerator and the limit of the denominator.
Step 1.3.1.1.1
Take the limit of the numerator and the limit of the denominator.
Step 1.3.1.1.2
As log approaches infinity, the value goes to .
Step 1.3.1.1.3
Since the exponent approaches , the quantity approaches .
Step 1.3.1.1.4
Infinity divided by infinity is undefined.
Undefined
Step 1.3.1.2
Since is of indeterminate form, apply L'Hospital's Rule. L'Hospital's Rule states that the limit of a quotient of functions is equal to the limit of the quotient of their derivatives.
Step 1.3.1.3
Find the derivative of the numerator and denominator.
Step 1.3.1.3.1
Differentiate the numerator and denominator.
