I. The domain of a function is the set of ordered first coordinates of the ordered pairs in that function. Sometimes the domain of a function is given explicitly. When the domain is not given explicitly, the convention is that the domain is the set of all real numbers which have real number images (images are second coordinates of pairs in a function.) 5 A. If h(x) = is given as the image formula for function h, according to the convention x+2 described above, what is the domain of h ? B. If h(x) = In(x+ 1) is given as the image formula for function h, according to the convention, what is the domain of h ? C. If A(x)=In x-3 is given as the image formula for function h, according to the convention, what is the domain of h
