anonymous · Answer

try plug in the x values into the function and see if it matches the y value

anonymous · Answer

i messed up

anonymous · Answer

$$y=6(0)-3$$$$y=6(1)-3$$ and so on

usukidoll · Answer

@saseal  based off the multiple choices.. we could use x = 0,2, 4 1 or -2 to see if one of them worked,

anonymous · Answer

yea theres 0,1,2,4

anonymous · Answer

okay

so what is the answer

@UsukiDoll  take over i gotta go to class!

usukidoll · Answer

whatttttttttt............  just plug in x = 0, x = 2, and x = 4

anonymous · Answer

then what shold i get

usukidoll · Answer

y should be -3 if x = 0
y should be 9 if x = 2
y should 21 if x = 4

anonymous · Answer

okay

usukidoll · Answer

the third choice is the answer.

anonymous · Answer

thank you

usukidoll · Answer
