Which of the following is not a value in the range of the function(-24)(0-4)(1-2)(314)?

As you cannot write ordered pairs in a question in this interface, you probably mean (-2,4), (0,-4), (1, -2), and (3,14), although the last one may not be what you meant.

Now to your question ... it is not clear.

1) The list of ordered pairs does represent a function, since all the x-values are different.

2) Perhaps the question is: "Which of the numbers 3, 1 and 4 are not values in the range of the function {(-2,4), (0,-4), (1,-2)}?" The range of a function is the set of y-values, {4, -4, -2}. Only 4 belongs to the range. Neither 3 nor 1 is a value in the range.
