Best ResponseYou've already chosen the best response.2A function must have exactly one "y value" for a given "x value". Look at the options, all of them are of form \(y=\pm \text{somthing}\), which means, the \(y\) values are not unique. What can you infer fromm this ?

Best ResponseYou've already chosen the best response.1It is not a function, because there are more than one y value?

Best ResponseYou've already chosen the best response.2I think, we may say the inverse of given function is a multivalued function. But, we cannot say the inverse is a function... @ribhu please enlighten me as you seem to have good real analysis knowledge :)
