Question

Let R={0, 1, 2, 3} be the range of h(x) = x - 7. The domain of h -1(x) is
{-7, -6, -5, -4}
{7, 8, 9, 10}
{0, 1, 2, 3}

Answer 1

well if you have function the the domain of the function is the range of the inverse

also the range of the function is the domain of the inverse...

I seem to recall something like that
