If mc019-1.jpg and n(x) = x – 3, which function has the same domain as mc019-2.jpg?

We know that m o n(x) = m(n(x))

This means           

                                     (x-3) + 5       x+2
                   m(n(x)) =   =
                                     (x-3) -1         x-4

The domain of this function is all real numbers - {4}

The function with the same domain is h(x) = 11/x-4

The correct answer is 7
