Set the denominator equal to zero for fractions with a variable in the denominator. When finding the domain of a fractional function, you must exclude all the x-values that make the denominator equal to zero, because you can never divide by zero. So, write the denominator as an equation and set it equal to 0. [2]

WebExample 5. Find the domain and range of the following function. f (x) = 2/ (x + 1) Solution. Set the denominator equal to zero and solve for x. x + 1 = 0. = -1. Since the function is undefined when x = -1, the domain is all real numbers except -1. Similarly, the range is all real numbers except 0. WebThe domain of a function is all the possible values of x's of ordered pairs; whereas the range of a function is all the possible values of y's of ordered pairs. You can easily find them by graphing the functions or ordered …
