Domain of radical function multiplied by x

The video tutorial reviews the previous class and introduces the concept of identifying the domain of a function. It discusses the properties of the function X, noting that it is linear and has no discontinuities. The tutorial explains the domain restrictions when dealing with radicals, emphasizing that the values under the radical must be greater than or equal to zero. The instructor demonstrates solving inequalities to find the domain, which is all numbers greater than 1/3. The video concludes with a discussion on graphing the domain and a reminder about multiplication and division rules.
