How do you find the domain of a function?
to find the domain first check all the possibilities of the denominator attaining a value of zero then if the function has any thing inside a square root, the expression inside the root must be always greater than or equal to zero.If the square root is in the denominator then the expression inside must be just greater than zero but not equal to zero.
