{(2, –2), (1, 5), (–2, 2), (1, –3), (8, –1)}
It is not a function by above definition(since, 1 have 2 images)
{(3, –1), (7, 1), (–6, –1), (9, 1), (2, –1)}
It is a function
{(6, 8), (5, 2), (–2, –5), (1, –3), (–2, 9)}
It is not a function(since, -2 have more than 1 image)
{(–3, 1), (6, 3), (–3, 2), (–3, –3), (1, –1)}
It is not a function (since, -3 have more than 1 images)
