The video tutorial explains the function F(X) = sqrt(2X - 3) and its domain. Initially, the implied domain is all real numbers, but due to the radical, the domain is restricted to values where 2X - 3 is greater than or equal to zero. The domain is solved to be from 3/2 to infinity. The tutorial also covers how to represent the domain graphically and the use of brackets and parentheses in domain notation.
