To be able to graph y=x^3+3x^2-6x​, let's first determine what time of equation is it.

The expression appears to be a cubic equation.

For a cubic equation, you must be familiarized that its standard graph appears to be like this:

Let's now plot the graph of the equation.

Step 1: Identify some points of the graph.

To be able to get the coordinates of some points that pass through the graph, we think of a value of x and substitute it to the equation to get the y.

We get,

x Computations y Coordinates

-4 = (-4)^3+3(-4)^2-6(-4) 8 (-4,8)

-1 = (-1)^3+3(-1)^2-6(-1) 8 (-1,8)

0 = (0)^3+3(0)^2-6(0) 0 (0,0)

1 = (1)^3+3(1)^2-6(1) -2 (1,-2)

2 = (2)^3+3(2)^2-6(2) 8 (2,8)

After testing different samples of x and getting its respective y coordinate, we plot the graph of the equation.
