PLEASE HELP!!which 2 orderes pairs would form a direct variation? I have been stuck on this for a long time!

If (x,y) represents a direct variation solution then. y=m⋅x for some constant m.

Given the pair (1.5,6) we have. 6=m⋅(1.5) →m=4. and the direct variation equation is. ...

If (x,y) represents an inverse variation solution then. y=mx for some constant m.

Given the pair (1.5,6) we have. 6=m1.5. →m=9.

That's how you find it. (:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
