 Now different functions have the same value for different arguments. For example, 3 is the value of the function Square root of x for 9 and the value of the function \(x+1\) for 2. Which of these arguments and functions is contained in the value 3? Since there is no principle that singles out one argument and function as constituting the value, we should abandon either the functional model of incompleteness or the idea that states of affairs have constituents. Later Frege takes the second option:
