Which set of ordered pairs represents a function?
{(-1,-6), (-1, -2),(5, -1), (7, -2)}
{(5,-9), (-2, - 7),(5,4), (3, 7)}
{(4,-4), (-4,-4), (-7, -2), (-6,6)}
{(-4,7), (-4, - 7),(-3,6), (-6, -6)}

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

ian gonna lie that is way to much
