It's a question that has always popped up in my head. How is f(x)= ±[itex]\sqrt{x}[/itex] not a function, if both the solutions are "symmetrical?"
Does this also mean that the inverse function of even or periodic functions aren't real functions either? Futhermore, does this somehow apply to three-variable graphs as well?
