Question

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 1

A. 4,5

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.
