I'm not understanding why this function is NOT one to one? How do I quickly see if this function is one to one? Im not getting the overall concept of this..
A function is "one to one" if and only if different values of the arguments give different values of the function.
A function of two variables, f(x, y) is "one to one" if and only if f(x, y)= f(x', y') implies that x'= x and y'= y. That is not the case here.
