A rule to be part of a function is that you cannot have the same value of x, for two or more different values of y.
In this case, we have that the points of the function are:
(0, -2), (1, 1), (-2, -8), (-1, -5), and (3, 7)
Out of the options we have, the point that we cannot have in this funcion is:
D:(-1,4)
this is because we already have a point that is (-1, -5). and if we include the point (-1, 4) we would have 2 different y values for x=-1, which are -5 and 4. And this violates the rule that a function cannot have two different y values for the same x value.
Answer: D (-1,4)
