finding equation of function from given figure












2














enter image description here
According to me the right answer is option 2 as it satisfies the point (2,-1) also. But answer says it's option 1 which is the answer. Iam not convinced with the answer. Is my answer correct?

    Your answer is correct, and is the only correct one among the three options.

As dxiv pointed out, your answer is correct. We can verify that by plugging $y=-1$ into the three equations given to see which equation yields $x=2$:



$$begin{align}
y-|y|&=-1-|-1|=-1-1=-2 :::large{times}\[1ex]
-(y-|y|)&=-(-1-1)=-(-2)=2 qquadcheckmark \[1ex]
y+|y|&=-1+1=0 hspace{3.4cm}largetimes
end{align}$$
