Answer this for i am very confused, i somehow got a slope of 8.

The slope is always rise/run.

In this situation, the rise is (-4) - (-1) as that gives the difference in the y values and this is = (-3).

The run is 1 - (-4) as this gives the difference in the x values and this is = 5.

Thus the slope is (-3) divided by 5.

This implies that:

Slope = negative(3/5)

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
