The domain of any graph depends on the vertex as well as the asymptotes. You can easily tell if the domain is all real numbers by looking at the graph and seeing that it goes clearly from -infinity to +infinity. If there is an asymptote that blocks it, then it will not be all real numbers.
Your answer would be 1.5, as that says 75 divided by 50
The length is 32 and the width is 1. 32÷2 is 16. 16-15 is 1. 32+32+1+1 is 66
