9.1 Graphing Quadratic Functions

Standard:

F.IF.7

  • 7. Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases.
  • 7a. Graph linear and quadratic functions and show intercepts, maxima, and minima.   

Essential Questions:

  • How are quadratic functions used to model, analyze, and interpret mathematical relationships?
  • What are the different ways to solve a quadratic equation, and when is each appropriate?
  • How can analytic and graphical methods be used to support each other in the solution of a problem?

Learning Targets:

  • I can graph a quadratic function expressed in symbolic form.
  • I can identify the vertex, the axis of symmetry, the roots, and the y-intercept by inspection of the graph of a quadratic function.
  • I can identify the domain and range, the interval behavior, and whether the function is increasing or decreasing and whether there are maximum and minimum values.
