WebThe problem with trying to find an inverse function for [latex]f(x)=x^2[/latex] is that two inputs are sent to the same output for each output [latex]y>0[/latex]. The function … WebAnother answer Ben is that yes you can have an inverse without f being surjective, however you can only have a left inverse. A left inverse means given two functions f: X->Y and g:Y->X. g is an inverse of f but f is not an inverse of g. So take any element x in X and g(f(x)=x.
