If y = f(x) then solution set is {x:x<-1}.

If y = f(x) ten solution set is (x:x>1}.

Then you have two shaded regions.

But you have (b) and (a) without any clue that the belong to domain of x.

Without more information about origin of (a) and (b), I don't know either.

Maybe someone with a graphing program will send a picture.

The program that makes the graph will have to make a choice.

If you have no better idea, why not go with something simple like the above?

If you are wrong, asking for more instruction will probably help.
