h(x)=x-7

h^{-1}(x)=x+7

From

range of h(x) = domain of h^{-1}(x)

and

domain of h(x) = range of h^{-1}(x)

We conclude that the domain of h(x) is the same as the range of

h^{-1}(x)=x+7

where the domain of h^{-1}(x) is {0,1,2,3}.

For example:

h^{-1}(0)=0+7=7

...

domain of h(x) is therefore {7,...}
