    if we define the first components to be inputs; and the second components to be output; then this is not a function

    If one input has more than one output, its not a function by definition

    Exactly because a function is defined as being one to one

    many to one is fine, one to one is invertible; but one to many is not a function

    x^2 is a function, but it is not one to one (-2)^2 = (2)^2 = 4
