Question 380520: Please help me:
2.If polynomial p(x)=2x^3 -3x^2-10 has exactly one real zero r, -1<=r<=1, which following is true: A. -1<0 B. 0<1 or C.other answer(explain)?
3. what is a portion of graph of y= y|-|-x|| ? graph it.
Answer by Fombitz(32388) (Show Source): 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||

Please correct and repost.
