AII.7b
The student will investigate and analyze functions algebraically and graphically. Key concepts include
b)   zeros;
Graphing calculators will be used as a tool to assist in investigation of functions.
Essential Knowledge and Skills 
  • Identify the domain, range, zeros, and intercepts of a function presented algebraically or graphically.
Essential Understandings
  • Functions may be used to model real-world situations.
  • A zero of a function is a value of x that makes f(x) equal zero.
