I have searched everywhere on ways to do these Combining Functions problem so here goes. Everywhere I look, this is only explained through actual functions. Ive yet to see one done with only the domain and range of a function.
Let f,g,h be functions with domain and ranges below: f has domain [-1,1) and range [0,2) g has domain [0,2) and range [-1,1) h has domain [1,3) and range [1,2)
For each of the following proposed new functions, specify its domain if it exists, otherwise state that the function does not exist.
(f+g), (f+h), (g o h), (h o g)
Any advice would be a godsend. I already have the answers, just looking for explanations for them.
