1. Use Descartes` Rule of Signs to determine the possible number of positive real zeros of the function.
F(x)=3x cube-4x squared-2x-4

***************x squared +11x+28
2. Graph: f (x)= ------------------------
***************x squared +8x+16

****************3x squared -3x-1
3. Graph: f (x)= ------------------------
***************x squared -x-2
