Best ResponseYou've already chosen the best response.1well if y is given in terms of x x in terms of y is the inverse

Best ResponseYou've already chosen the best response.1This may sound like a dumb question, but the y turns back into an x, making root y into a root x making it x^2?

Best ResponseYou've already chosen the best response.1yep that is because we always report a function in the form y=something
