You can put this solution on YOUR website! According to standard form, this vertex is (-2,-4). Pick your other points according to which you like. Try to do simple ones. x=0, x=1, x=-4, whichever else.

To graph the parabola, plot the vertex and four additional points, two on each side of the vertex. Then click on the graph icon.
From the above equation, vertex of parabola, or (h, k) = (- 2, - 4)
Two x-values to the LEFT of h = - 2 are:  , which will give the two points, (- 3, - 3) and (- 4, 0)
Two x-values to the RIGHT of h = - 2 are:  , which will give the two points, (- 1, - 3) and (0, 0)
Use these four points, and the vertex to graph the parabola!
