Domain Function Rational
To find these x values to be excluded from the domain of a rational function equate the denominator to zero and solve for x for example the domain of the rational function is the set of all real numbers except x 0.
Domain function rational. Learn how to find the domain of rational functions. Domain of a rational function the domain of a rational function includes all real numbers except those that cause the denominator to equal zero. To find these x values to be excluded from the domain of a rational function equate the denominator to zero and solve for x.
In general to find the domain of a rational function we need to determine which inputs would cause division by zero. For example the domain of the parent function f x 1 x is the set of all real numbers except x 0.
