You can put this solution on YOUR website!
2.) Here is a graph of p(x).
It has a real root between 2 and 3.
The other two roots are complex.
I'm not sure I understand your question?

3). You are missing an operator in your equation or something is wrong with your equation.
After the y on the right hand side you should have an operator (+,-,*,/) and then I think you mean to write the absolute value of the negative of the absolute value of negative x, but I'm not sure.
y= y|-|-x||
