Answer 2

what do u think it is

Answer 3

the fourth graph?

Answer 4

it says x>-1/2

this equation doesn't contain y
so y can be anything

but we need to focus upon x
it says that that x should be greater than -1/2

but the graph 4 that u chose has a solid boundary which means that the points on edge are included.
for example the point (-1/2, 1) is included but hey the x cordinate of this point is -1/2 and should should not happen cause x>-1/2

so graph 4 is wrong
what do u think the answer is..

Answer 5

so the first graph

Answer 6

in 1st graph all x cordinates are less than -1/2
but x>-1/2
so it is wrong

Answer 7

lol -_-

Answer 8

:)

Answer 9

2nd graph is correct
