We plug in the values of x and y as shown below:
the given equation is
As we can see the equation is of the form of a parabola . The equation of parabola is given as
in the equation h = -2 and k =0
On plotting the above parabola on graph is as shown on the sheet
The vertex is (h,k) = (-2,0)
The y intercept is (0+2)^2 = 4. So, y intercept is (0,4)
The x intercept in this case is the same as vertex = (-2,0)
Now, we graph the parabola as shown in the attachment
