a function will not have any repeating x values....all the x values must be different....now it can have repeating y values, just not the x ones.

so ur function is { (3,-1),(7,1),(-6,-1),(9,1),(2,-1)}.....because all the x values are different

Answer:

{(3, –1), (7, 1), (–6, –1), (9, 1), (2, –1)}

Explanation:

{(2, –2), (1, 5), (–2, 2), (1, –3), (8, –1)} is not a function because 1 have two different images.

{(6, 8), (5, 2), (–2, –5), (1, –3), (–2, 9)} is not a function because -2 have two different images.

{(–3, 1), (6, 3), (–3, 2), (–3, –3), (1, –1)} is not a function because -3 have two different images.

{(3, –1), (7, 1), (–6, –1), (9, 1), (2, –1)} is a function because all x values has one only image value.
