spacebar to place a point 1 to delete the last point you placed 2 to delete all the points 3 to graph the parabola the first point is the vertex, and the second point is what the parabola should go through.
learned this stuff in high school lol vertex = (h, k) vertex form: a(x-h)^2+k equation to solve for a: through point = (x, y) y = a(x-h)^2+k // first step y-k = a(x-h)^2 // second step a = (y-k)/(x-h)^2 // final equation
