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.
How do you find asymptotes of an equation?
by following these steps:
- Find the slope of the asymptotes. The hyperbola is vertical so the slope of the asymptotes is.
- Use the slope from Step 1 and the center of the hyperbola as the point to find the point–slope form of the equation.
- Solve for y to find the equation in slope-intercept form.
What is vertical asymptote?
Vertical asymptotes are vertical lines which correspond to the zeroes of the denominator of a rational function. (They can also arise in other contexts, such as logarithms, but you’ll almost certainly first encounter asymptotes in the context of rationals.)
How do you find Asymptotes algebraically?
To summarize, the process for working through asymptote exercises is the following:
- set the denominator equal to zero and solve (if possible) the zeroes (if any) are the vertical asymptotes (assuming no cancellations)
- compare the degrees of the numerator and the denominator.
What is the equation for a vertical asymptote?
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).

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.
What are the rules for vertical asymptotes?
To determine the vertical asymptotes of a rational function, all you need to do is to set the denominator equal to zero and solve. Vertical asymptotes occur where the denominator is zero. Remember, division by zero is a no-no. Because you can’t have division by zero, the resultant graph thus avoids those areas.
What are the rules for 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 the asymptotes of a function?
Finding Horizontal Asymptotes of Rational Functions
- If both polynomials are the same degree, divide the coefficients of the highest degree terms.
- If the polynomial in the numerator is a lower degree than the denominator, the x-axis (y = 0) is the horizontal asymptote.
