A.
{(–3, 2), (–2, 3), (–1, 2), (0, 4), (1, 1)}

B.
{(–3, 2), (–1, 3), (–1, 2), (0, 4), (1, 1)}

C.
{(–3, 2), (–2, 3), (–1, 1), (0, 4), (0, 1)}

D.
{(–3, 3), (–2, 3), (–1, 1), (0, 4), (0, 1)}

Answer 1

all of ur points are set up (x,y). A function will not have any repeating x values. They can have repeating y values, just not the x ones.

so ur function is : A

Answer 2

The answer is A {(-3,2),(-2,3),(-1,2),(0,4),(1,1)}
