A parabola has a vertex at (0,0). The focus of the parabola is located on the positive x-axis. Which part of the graph will be the directrix pass through? To see why the formula in Theorem2.2produces the vertex, consider the graph of the equation y= a(x h)2+k. When we substitute x= h, we get y= k, so (h;k) is on the graph. If x6= h, then x h6= 0 so ( x h)2 is a positive number. If a>0, then a(x h)2 is positive, thus y= a(x h)2+k is always a number larger than k.
