Does anyone know about composite functions? For what types of functions will (g of f)(x) and (f of g)(x) both equal x? Please explain!

OpenStudy (anonymous):

Could you explain?

OpenStudy (anonymous):

Oh no, I don't think you're wrong I'm just wondering how and why.

OpenStudy (anonymous):

Oh, I think I get it now. Thank you!

OpenStudy (anonymous):

Wait, how do they both equal x even though they have different lines when you graph them? I just don't understand how the domain and range are opposites, but they equal each other.

OpenStudy (anonymous):

Oh okay! Got it!
