# What is a rational parent function?

A rational parent function is the most basic rational function whose form is imitated by all other rational functions, and it is written as f(x) = 1 / x. Rational functions represent the division of two polynomials where the denominator must contain a variable.

The domain and range of a rational parent function is the set of all real numbers with the exception of 0. The graph of a rational function is a hyperbola. Excluded values are x-values that result in undefined y-values, hence they should be excluded from the domain. The parent rational function has the x- and y-axes as its asymptotes.

Q:
## How does "X" vary from "Y"?

A: In functions, "Y" is generally used in place of f(X) to represent the output of the function. This output is dependent on the value of the input, which is ... Full Answer >Filed Under: -
Q:
## How do you graph piecewise functions?

A: A piecewise function is simply two or more functions put together with non-intersecting domains. Once each domain has been determined and the endpoints hav... Full Answer >Filed Under: -
Q:
## How do you convert point-slope form to slope-intercept form?

A: Because most linear functions are given in slope-intercept form, they can be easier to work with than point-slope form. To convert, you must isolate the y ... Full Answer >Filed Under: -
Q:
## What is the definition of "quadratic function"?

A: A quadratic function is a function of the form f(x) = ax^2 + bx + c where a, b and c are constants. Part of the definition of a quadratic function is that ... Full Answer >Filed Under:
