Outcomes

In this lesson you will

  • Use completion of the square (with aid of algebra tiles if necessary) on the general form of a quadratic function to derive its transformational form.
  • Use the transformational form of a quadratic function to identify properties of the corresponding parabola, especially the location of its vertex.
  • Use the transformational form of a quadratic function to solve maxima and minima problems.

By the end of this section you should be able to:

  • Analyze and describe the characteristics of quadratic functions.
  • Solve problems involving quadratic equations.
  • Analyze scatter plots, and determine and apply the equations for curves of best fit, using appropriate technology.
  • Describe and translate between graphical, tabular, written, and symbolic representations of quadratic relationships.
  • Demonstrate an understanding of the relationships that exist between arithmetic operations and operations used when solving equations.
  • Translate between different forms of quadratic equations.
  • Describe and interpret domains and ranges using set notation.
  • Demonstrate an understanding of how parameter changes affect the graphs of quadratic functions.
