Answer:
3rd option (7.-8),(-2,-6),(-1,-1),(-5,-1)
Step-by-step explanation:
A function is an input which has only one output (x,y)
1st option has 2 pairs which have 1 as x, so we can cross that one out.
2nd option has 2 pairs that have 9 as x
4th option has 2 pairs which have 8 as x
Which leaves you with the 3rd option as the only correct answer.
