Which relation is a function {(2, 3), (1,5), (2,7)}
{(-1,5), (-2,6), (-3,7)}
{(11,9), (11,5), (9,3)}
{(3,8), (0,8), (3,-2)}

The relation that is a function is{ (-1,5), (-2,6), (-3,7) }. A function will not have any repeating x-values, they all have to be different.

can you put the picture up?

step-by-step explanation:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
