The video tutorial explains the functions F(x) = x^2 - 1 and G(x) = sqrt(x) - 1, focusing on domain restrictions. It highlights the importance of considering the domain of the function being plugged in during composition. The tutorial demonstrates the composition of F(G(x)), simplifies it, and emphasizes maintaining the original domain restrictions. The conclusion reiterates the significance of domain awareness in function composition.
