The vertex form of the equation of a parabola is ( y = a(x - h)^2 + k ), where (h, k) is the vertex. Given the focus at (12,22) and a directrix of y=11, the vertex of the parabola is the midpoint between the focus and the directrix, which is (12, 16.5). Therefore, the vertex form of the equation of the parabola is ( y = a(x - 12)^2 + 16.5 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
