Does y = x square have an inverse function

(2) The necessary conditions for the existence of inverse function of function are that the domain of definition and range of value of function are one-to-one mapping; (3) the monotonicity of a function and its inverse function is consistent in the corresponding interval; (4) most even functions do not have inverse function (the only even function with inverse function is f (x) = a, X ∈ {0})
