Which of the relations given by the following sets of ordered pairs is not a function? o {(-5,2), ( – 3,3), (0, 6), (0,4), (2, 1)}
o {(0, – 8), (1, – 8), (2, – 8), (3, – 8), (4, - 8)}
o {(-6, - 1), (-4, - 2), (-9, - 5), (-3, -1), (- 1, – 7)}
o {( – 4,7). ( - 2,5), (- 1,3), (2,5),(4, - 6)

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

the two may have that, even a breakdown is probably offered

the answer is (-4,-4)

hope this ! : d

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
