The function f (x) = x2 has a domain of all real numbers (x can be anything) and a range that is greater than or equal to zero Two ways in which the domain and range of a function can be written are interval notation and set notation Find the domain and range of the function f(x) = (x^2 9)/(x 3) asked in Sets, Relations and Functions by RamanKumar (499k points) sets;Algebra Find the Domain and Range f (x)=2/x f (x) = 2 x f ( x) = 2 x Set the denominator in 2 x 2 x equal to 0 0 to find where the expression is undefined x = 0 x = 0 The domain is all values of x x that make the expression defined Interval Notation
