Domain and Range

Domain and Range

Domain

• When it comes to domain think how far left, and how far right.

  
  

    

• Remember the X-axis goes left to right.

  
  

• If the dot is open, then you use these inequalities <,>.

  
  

    

• If the dot is closed or shaded, then you use these inequalities ≤,≥

Range

• When it comes to range, it is the y variable

• It can also be called the output

• You may also see it called the dependent variable

• When trying to figure out the range, figure out, how far up, and how far down
