SOL 
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.

Vertical Line Test: In your own words, explain how and why the
vertical line test works.
 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.
