First, make sure the function is in standard form. Then find the x-value of the vertex by taking negative "b" and dividing by 2 times "a." To get the y-value of the vertex, plug the x-value you just found into the original equation.
Then find the y-intercept by plugging in 0 for x. Finally, since the parabola is symmetrical, count how far you moved from the vertex to the y-intercept, and count the other way to get a third point.
