Vertex Form of a Quadratic Model

f(x) = y = a(x - h)^2 + k

*the vertex is the point (h, k)
*very similar to y = a|x - h| + k, which we have explored in the past

Graphing a Quadratic Model in Vertex Form
1) Graph the vertex (h, k) on the coordinate plane and draw in the axis of symmetry.
2) Find another appropriate point on the parabola by selecting an appropriate value of x.
3) Plot the new point and its reflection on the coordinate plane.
4) Once you have the vertex, a point to the left, and a point to the right, it is time to sketch the curve.
