All done

Answer 1

Sad parabola, which is y=-a(x-h)^2+k, consist of maximum vertex, because the vertex reaches the top of all x and y values of the parabola

Happy parabola on the other hand, consist of minimum vertex because the vertex is located on the lowest point of the parabola. The equation will always look like this, which is y=a(x-h)^2+k with a positive a
