What is a rational function?

Back

A rational function is a function that can be expressed as the quotient of two polynomials, where the denominator is not zero.

What is the domain of a rational function?

Back

The domain of a rational function is all real numbers except where the denominator equals zero.

What is the range of a rational function?

Back

The range of a rational function is the set of all possible output values, which can vary based on the function's behavior.

How do you find horizontal asymptotes?

Back

To find horizontal asymptotes, analyze the degrees of the numerator and denominator polynomials.

What is the significance of the degree of the numerator and denominator in rational functions?

Back

The degree of the numerator and denominator determines the behavior of the function at infinity and the existence of horizontal asymptotes.

What is a hole in a rational function?

Back

A hole occurs in the graph of a rational function at a point where both the numerator and denominator are zero, indicating a removable discontinuity.
