How do you find the asymptote of an equation?
Vertical asymptotes can be found by solving the equation n(x) = 0 where n(x) is the denominator of the function ( note: this only applies if the numerator t(x) is not zero for the same x value).
Find the asymptotes for the function .
The graph has a vertical asymptote with the equation x = 1.
How do you find the horizontal asymptote?
To find horizontal asymptotes:
- If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0).
- If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.

How do you find the asymptote of a graph?
Process for Graphing a Rational Function
- Find the intercepts, if there are any.
- Find the vertical asymptotes by setting the denominator equal to zero and solving.
- Find the horizontal asymptote, if it exists, using the fact above.
- The vertical asymptotes will divide the number line into regions.
- Sketch the graph.
How do you find Asymptotes using limits?
Vertical Asymptotes Using Limits –
How do you find asymptotes and holes?
Set each factor in the denominator equal to zero and solve for the variable. If this factor does not appear in the numerator, then it is a vertical asymptote of the equation. If it does appear in the numerator, then it is a hole in the equation.
What are the rules for horizontal asymptotes?
The three rules that horizontal asymptotes follow are based on the degree of the numerator, n, and the degree of the denominator, m.
- If n < m, the horizontal asymptote is y = 0.
- If n = m, the horizontal asymptote is y = a/b.
- If n > m, there is no horizontal asymptote.
How do you find vertical and horizontal asymptotes?
The vertical asymptotes will occur at those values of x for which the denominator is equal to zero: x − 1=0 x = 1 Thus, the graph will have a vertical asymptote at x = 1. To find the horizontal asymptote, we note that the degree of the numerator is two and the degree of the denominator is one.
What is the property of log?
Recall that we use the product rule of exponents to combine the product of exponents by adding: xaxb=xa+b x a x b = x a + b . We have a similar property for logarithms, called the product rule for logarithms, which says that the logarithm of a product is equal to a sum of logarithms.
How do you find the domain and vertical asymptotes of a function?

What is the value of ln 0?
ln(0) = ? The real natural logarithm function ln(x) is defined only for x>0. So the natural logarithm of zero is undefined.
