Acoording to function y=|x|
then any negative value of x function give positive value then y always be positive value its depends uopn a A,B,C,D.
for graph A and B is positive then cofficient A and B is positive. and function C and D is negative then cofficient C and D is negative.
Cofficient with greatest value is C then D then B then A and is decide upon curve is sharp from.
Cofficient with closest to zero is A,B,D then C it depends upon the closest with x axis .
