1. 1.Domain

   • 2.Vertical Asymptotes
     • 3.Horizontal Asymptotes
       • 4.Y-intercept
         • 5.X-intercept
           • 6.Hole/Empty Point
             • 7.Range
               • 8.Graph
                 • f(x)= x-4/x^2-16
                   • Domain≠4,-4 / Range≠0 / VA: x=-4 / HA: y=0 / Y-int: (0, 1/4) / X-int: --- / Hole: x=4
               • y≠? (Horizontal Asymptote)
             • x value that is cancelled in an equation x=?
           • y=0 in an equation
         • x=0 in an equation
       • y=a^n/b^m
         • If n=m then y=a/b
         • If n>m then it doesn't exist
         • If n<m then y=0
     • x=? (Denominator)
   • x≠? (Denominator)
