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

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

Answer 1

Answer 2

Ok a function is a group of values where there is only one y value for a single x
Meaning that x can only be associated with one y value
We know that a set of points in the form (x,y) where x is the first point and y is the second paired coordinate.

Answer 3

So lets look at option A
Since there is (0,4) and (0,1) There are 2 y values ~ 4 and 1 which are associated to one x-value which is 0 in this case So option A isnt a function

Answer 4

nope

Answer 5

What nope?

Answer 6

u said it isnt

Answer 7

Ok now lets go to Option B

Answer 8

Lets look through all the pairs

Answer 9

i thinks its D

Answer 10

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

(–1, 3), (–1, 2) - There is one x-value for 2 y-values
So this aint an option

Answer 11

B is also not option for the same reason A isnt an option

Answer 12

So the answer is C

Answer 13

that was my next option

Answer 14

Yuppp :)
