Explanation & Answer
Is this the whole question? If so, the domain of h^(x) is NOT the correct answer to the R = {0,1,2,3} for h(x)= x-7. h^-1(x) implies 1/x-7 (the reciprocal of h(x)). The question says "The domain of h^-1(x) is...is {0,1,2,3} the correct answer. Is there something else that is supposed to go in between the two "is"?
