Which of the following lists of ordered pairs is a function? TEN POINTS PLEASE ANSWER CORRECTLY AND DONT JUST STEAL THE POINTS (-1, 2), (5, 6), (-1, 7), (9,11)
(5, 7), (6, 8), (3, 2), (-4, 5)
(6, 8), (7, 3), (4, 2), (4, 1)
(9, 0), (6, -1), (9, -4), (8, 2)

im pretty sure all of them

Step-by-step explanation:

Here you are (-1, 2), (5, 6), (-1, 7), (9,11)

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

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
