Answer:

y=3x(x+1)(x-2)=3x^3-3x^2-6x

Step-by-step explanation:

The polynomial function can be written in the form:

y=a(x-x1)(x-x2)(x-x3)

where

x1=-1

x2=0

x3=2

Therefore

y=a(x+1)(x-0)(x-2)=a(x^2+x)(x-2)=a(x^3-x^2-2x)

To find the value for "a" we use the info about the line passing in (1,-6):

-6=a(1-1-2)

a=3

y=3x(x+1)(x-2)=3x^3-3x^2-6x
