## How do you find the asymptote equation?

How to Find Horizontal Asymptotes?

1. If the degree of the polynomials both in numerator and denominator is equal, then divide the coefficients of highest degree terms to get the horizontal asymptotes.
2. If the degree of the numerator is less than the degree of the denominator, then the horizontal asymptotes will be y = 0.

## What is asymptote of parabola?

In analytic geometry, an asymptote of a curve is a line such that the distance between the curve and the line approaches zero as one or both of the x or y coordinates tends to infinity. But in this case, the distance is already infinity and doesn’t approach it. Hence, there is no asymptote for parabola.

What is number asymptote?

An asymptote is a line that a graph approaches without touching. If a graph has a horizontal asymptote of y = k, then part of the graph approaches the line y = k without touching it–y is almost equal to k, but y is never exactly equal to k.

### What is asymptote and example?

The asymptote (s) of a curve can be obtained by taking the limit of a value where the function does not get a definition or is not defined. An example would be \infty∞ and -\infty −∞ or the point where the denominator of a rational function is zero.

### Do all parabolas have asymptotes?

Even though parabolas and hyperbolas look very similar, parabolas are formed by the distance from a point and the distance to a line being the same. Therefore, parabolas don’t have asymptotes.

How do you draw asymptotes?

The line x=a is a vertical asymptote if the graph increases or decreases without bound on one or both sides of the line as x moves in closer and closer to x=a . The line y=b is a horizontal asymptote if the graph approaches y=b as x increases or decreases without bound….Section 4-8 : Rational Functions.

## What are the 3 different cases for finding the horizontal asymptote?

There are 3 cases to consider when determining horizontal asymptotes:

• 1) Case 1: if: degree of numerator < degree of denominator. then: horizontal asymptote: y = 0 (x-axis)
• 2) Case 2: if: degree of numerator = degree of denominator.
• 3) Case 3: if: degree of numerator > degree of denominator.

## How do you find the Directrix of a parabola?

How to find the directrix, focus and vertex of a parabola y = ½ x2. The axis of the parabola is y-axis. Equation of directrix is y = -a. i.e. y = -½ is the equation of directrix.
