## What is the correct procedure in finding the zeros of a rational function?

To find the zeroes of a rational function, set the numerator equal to zero and solve for the \begin{align*}x\end{align*} values.

When a hole and a zero occur at the same point, the hole wins and there is no zero at that point.

## How do you find Asymptotes?

**The horizontal asymptote of a rational function can be determined by looking at the degrees of the numerator and denominator.**

- Degree of numerator is less than degree of denominator: horizontal asymptote at y = 0.
- Degree of numerator is greater than degree of denominator by one: no horizontal asymptote; slant asymptote.

## How do you find the zeros of a polynomial function?

**Find zeros of a polynomial function**

- Use the Rational Zero Theorem to list all possible rational zeros of the function.
- Use synthetic division to evaluate a given possible zero by synthetically dividing the candidate into the polynomial.
- Repeat step two using the quotient found with synthetic division.
- Find the zeros of the quadratic function.

## How are Asymptotes and zeros related?

The vertical asymptotes come from the zeroes of the denominator, so I’ll set the denominator equal to zero and solve. Since the degree is greater in the denominator than in the numerator, the y-values will be dragged down to the x-axis and the horizontal asymptote is therefore “y = 0”.

## 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.)

## Are holes and zeros the same thing?

3 Answers. Both the numerator and the denominator being zero is a necessary but not sufficient condition for a hole; see for example the function f(x)=x+1(x+1)2. The difference between a hole and a vertical asymptote is that the function doesn’t become infinite at a hole.

## How do you solve rational expressions?

**The steps to solve a rational equation are:**

- Find the common denominator.
- Multiply everything by the common denominator.
- Simplify.
- Check the answer(s) to make sure there isn’t an extraneous solution.
