Recall that the domain of a function is the set of possible input values (x-values) of the function. For a rational function, the denominator cannot be zero and for radical functions, the value inside the radical cannot be negative. Thus, to find the domain of a rational function with radicals in both the numerator and the denominator, we set up the value inside the radical numerator as an inequality greater than or equal to 0 and solve the inequality for the variable. We also set up the value inside the radical denominator as an inequality (strictly) greater than 0 and solve the inequality for the variable. The set of values satisfying both inequalities is zero is the required domain.\n
