Algebra  1  Notes    9.17.13    

Discrete  vs.  Con8nuous    Discrete  data  is  counted,  con8nuous  data  is  measured    Discrete  examples:  

 how  many  students  are  in  class    the  number  of  green  m&m’s  in  the  bag.    how  many  marbles  are  put  in  the  container  

 Con8nuous  examples:  

 a  person’s  height    8me  in  a  race    a  dog’s  weight    length  of  a  car  

   

Intervals  An  interval  is  all  the  numbers  between  two  given  numbers.    

 Iden8fying  intervals  on  a  graph                      3    with  constant  rate  of  change.          2  

   Label  each  interval                                                                                      1  

                 3  intervals,  each  with  a  constant                  rate  of  change  

 Domain  is  the  interval  of  all  x  values    Range  is  the  interval  of  all  y  values    For  the  graph  to  the  right  and  interval  2  Domain  is  wriKen  [2,3]  Range  is  wriKen  [5,40]    Interval  Nota8on  []  endpoints  included,  ()  endpoints  excluded
