i once tried claiming my hand had a seizure in the middle of the test, but it didn't work out too well. Try looking for online sources. If it still doesn't work, grab your textbook and shoot a couple questions on here. I'll take a look-see.

you start with quadratic equation
$$y = ax^{2} +bx+c$$
first thing is find the vertex (min or max of curve)
vertex = (h,k)
$$h = \frac{-b}{2a}$$
plug "h" into equation to get "k"
next plot the y-intercept which is (0,c)
next pick 2 points on either side of vertex....
example if vertex is (2,2) then choose x_values 0 and 4 or  1 and 3
plug those into equation to get y_values
plot those points
Finally connect the points and you have your parabola :)
