1. Visualizing Relationships in Data

   • Independent
     • x-axis
     • Input
       • Inputs can only have one output
   • Dependent
     • y-axis
     • output
   • Function
     • Each input can only have one Output
     • A relation where each input has only one output
   • Domain
     • set of all inputs for the function
   • Range
     • set of all possible outputs resulting for the values of the domain

2. Graphs

   • Constant
     • f(x)=c
   • Linear
     • f(x)=x
   • Absolute Value
     • f(x)=|x|

3. Toolkit

   • Absolute value
     • The distance between zero
   • When x or / by a negative, flip the symbol
