OBJ: Sketch, by hand, the graph of y = a(x – h)^2 + k by applying transformations to the graph of y = x^2. |
Solve problems arising from a realistic situation represented by a graph or an equation of a quadratic relation,
with and without the use of technology. | Explain the roles of a, h, and k in y = a(x – h)^2 + k, using the
appropriate terminology to describe the transformations, and identify the vertex and the equation of the axis of
symmetry.
