Finding the Domain of a Function - Concept

Concept Concept (1)

Certain functions, such as rational and radical elementary functions, have instances of restricted domains. When finding the domain of a function, we must always remember that a rational function involves removing the values that could make the denominator of a fraction zero. Finding the domain of a function that is radical means not making the radical negative.
