Question

If f(x)=√x - 7 and g(x) = 9x-5 which statement is true?​

Answer 1

Answer:-7 if you allow complex numbers is in the domain of f of g. It is not in the domain if you disallow complex values

Step-by-step explanation:the domain is the set of x variables that produce a value for y. If you plug in -7 for x you get a negative value in the radical producing an imaginary number. If you allow complex values then x is in the domain. Otherwise it is not
