In this problem, we want to find the vertex, focus, axis, and directrix of the given parabola, and then sketch it.
00:08
Y is equal to one -half x squared.
00:11
This question is challenging our knowledge of conic sections, in particular, the conic section known as a parabola.
00:17
Parabolas are of the form a, x minus h squared equals y minus k, with the following information.
00:23
The vertex is at hk, the focus is at hk plus 1 over 4a, the directrix is y equals k minus 1 over 4a, and the axis is x equals h.
00:31
If we can extract h, k, and a from our given parabola equation, we can easily find all of these quantities and then draw...
