A.7- The student will investigate and analyze function (linear and quadratic) families and their characteristics both algebraically and graphically, including
a)   determining whether a relation is a function;
e)   finding the values of a function for elements in its domain; and
f)   making connections between and among multiple representations of functions including concrete, verbal, numeric, graphic, and algebraic

  1. Vertical Line Test: In your own words, explain how and why the vertical line test works.
  2. Functions: The solution to a function depends upon the value that is entered into the function. For example, the size of a bubble depends upon the amount of gum eaten. Write five functions using the format "_____ depends upon _____" and give an explanation or draw a picture to show your reasoning.
