Graphing Functions and Descartes’ Rule of Signs
November 5th, 2022
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
