Answer:
(3x²-x-2) (x+2) -first choice
Explanation:
First we notice that when x → - ∞ the y or f(x) → -∞ because the graph goes on the negative side of the y-axis (down) as we move on the left ( where x is negative)
Second we notice that the graph touches the x-axis at x= -2 so one of the roots is -2
The equation (3x²-x-2) (x+2) has a root at -2 because x+2= 0 will give x=-2
