## How do I find the domain and range of a function?

To find the excluded value in the domain of the function, equate the denominator to zero and solve for x .

So, the domain of the function is set of real numbers except −3 .

The range of the function is same as the domain of the inverse function.

So, to find the range define the inverse of the function.

## How do you find the range?

Summary: The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

## How do you find vertical asymptotes step by step?

To find the vertical asymptote(s) of a rational function, simply set the denominator equal to 0 and solve for x. We mus set the denominator equal to 0 and solve: This quadratic can most easily be solved by factoring the trinomial and setting the factors equal to 0. There are vertical asymptotes at .

## How do you find a function?

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.

## 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.
