Subtracting linear functions to find domain

The video tutorial explains how to subtract two functions, F(x) and G(x), emphasizing the importance of using parentheses to correctly group terms. It demonstrates distributing the negative sign and combining like terms to simplify the expression. The tutorial also covers the domain of linear equations, noting that subtracting functions does not restrict the domain, which remains all real numbers. The video concludes by summarizing the effects of adding and subtracting functions.
