WebDomain and Range of a Rational Function Division by zero in a function is never allowed, so the domain for all rational functions is any real number except for anything that results in the denominator equaling zero. For example, f (x) = 5/x has a domain of all real numbers except for zero, because 3/0 is undefined. WebEx: The Domain of Rational Functions How To: Given a function written in equation form including an even root, find the domain Identify the input values. Since there is an even root, exclude any real numbers that result in a negative number in the radicand. Set the radicand greater than or equal to zero and solve for x x.

WebThe first example is a rational function where x cannot equal to 0, so any value of x that makes denominator 0 will produce a hole in the domain. The second function is a square root function which has an end point and goes to positive (or negative) infinity. Different functions have different domains. 1 comment.
