Finding the domain of radical functions video involves domain, domain of a function, functions, number sense, numbers, radical functions, radicals. The video tutorial is recommended for 1st Grade, 2nd Grade, 3rd Grade, 4th Grade, 5th Grade, 6th Grade, 7th Grade, 8th Grade, 9th Grade, 10th Grade, 11th Grade, and/or 12th Grade Math students studying Algebra, Geometry, Trigonometry, Probability and Statistics, Arithmetic, Basic Math, Pre-Algebra, Pre-Calculus, and/or Advanced Algebra.

The domain of a given function is the set of "input" values for which the function is defined. For instance, the domain of cosine would be all real numbers, while the domain of the square root would only be numbers greater than or equal to 0 (ignoring complex numbers in both cases). In a representation of a function in a xy Cartesian coordinate system, the domain is represented on the x axis.

The radical symbol is used to indicate the nth root of a number.
