111.33.b.7

(7) Quadratic and square root functions. The student interprets and describes the effects of changes in the parameters of quadratic functions in applied and mathematical situations. The student is expected to:

• (A) use characteristics of the quadratic parent function to sketch the related graphs and connect between
  the y = ax² + bx + c and the
  y = a (x - h)² + k symbolic representations of quadratic
  functions; and

• (B) use the parent function to investigate, describe, and predict the effects of changes in a, h, and k on the graphs of y = a (x - h)² + k form of a function in applied and purely mathematical situations.
