Any ideas?

the third one.

Looks like the right answer to me.

anonymous · Answer

It's a sine graph so it'll start at the midline, 1, and it goes up to 5. 5-1=4

haseeb96 · Answer

A is the correct answer.

kainui · Answer

You can also tell the amplitude is 4 because the lowest point it touches is -3 and the highest point is 5, so it has a total span of 8 units, meaning it must be wobbling up and down with an amplitude of half that, which is 4.

Check your answer @Haseeb96 you're wrong, @wrstlr3232 is completely right.

i was thinking A but i didnt even think about it being a sine graph
