Chapter 1

1. Relation

   • any ordered pair

2. Ordered Pair

   • (3,2) = (Input, Output)
   • Domain, Range

3. Function

   • each input = only one output
     • the x value goes up by the same amount

4. Mapping

   • a system for the domain and range to be compared to see if they have similar outputs
     • x=-4, undefined slope
     • y= 7, slope is zero

5. Independent v. Dependent

   • x= Independent y= Dependent

6. Inequalities

   • Ex: x>5
   • When divided by a negative, flip the symbol

7. Solving for "r"

   • The goal is to get "y" alone
