A good one...let's start with stmt 2

|3 – y| = 11

y should be -8 and 14--insufficent

stmt1--no info for x and y--insufficent

combine both,

re arrange 1st statement

y=2 +3|x^2 – 4|

from stmt 2,we ve one -ve and one +ve value...

because equation of x is in absolute

no chance we ll get negative value

anser should be 14---Sufficient

C---hope it clears
