Firstly while looking at the question we can eliminate Answer choice E as this question consists of an absolute sum with a range of less than value (10 in this case). Thus there are finite set of possibilities.
After this we can determine the critical points -1,0,3 and check for the no of integer values that satisfy the equation
Now note all the 3 critical points satisfy the equation hence we have 3 values to start with.
Range 1: x<-1---------Only -2 satisfies this. Any value less than -2
