Domain And Range Of A Rational Function
The domain of a rational function consists of all the real numbers x except those for which the denominator is 0.
Domain and range of a rational function. Let us consider the rational function given below. A rational function is a function of the form f x p x q x where p x and q x are polynomials and q x 0. Performance task in general mathematics domain and range of rational functions complete the table below as.
Finding domain of the inverse of rational function. How to find the range of a rational function. Therefore the domain is.
The idea again is to exclude the values of x that can make the denominator zero. Y 1 x 2 to find range of the rational function above first we have to find inverse of y. Let y f x be a function.
Obviously that value is x 2 and so the domain is all x values except x 2. How to find the domain of a rational function. View domain and range of rational functions docx from bio 123 at university of phoenix.
Range is nothing but all real values of y for the given domain real values of x. To find these x values to be excluded from the domain of a rational function equate the denominator to zero and solve for x.
