Which ordered pair can be added to the table so that y is still a function of x
A. 4,5
B. 2,5
C. 0,4
D. -2,4

Answer:
A. 4,5
Step-by-step explanation:
No x-value can be repeated if the relation is to remain a function. The x-values already in the table are {-4, -2, 0, 2}. This list eliminates all answer choices except the first one: (4, 5) may be added to the table.
