Hello, forgive me if I used bad english, I am not a native speaker.

 

Anyhow: I have to decide the set of coordinates looking at the grafs intersections.  (I hope you understand that)

 

This is my function: f(x)=1/4*x3-x2-x+4

 

When you plot the function you see that the intersections is (-2,0) (2,0) and (4,0)

 

BUT I have to use a command to find these three intersections, plzz help me!

 

THANK YOU indeed.

 

 

[point of] intersection
