Enter each answer as a whole number like 4 0 or 253 or DNE f
     Enter each answer as a whole number (like -4, 0, or 253) or DNE for undefined or Does Not Exist.  f(7) =  lim_x rightarrow 8^- f(x) =  lim_x rightarrow 8^- f(x) =  lim_x rightarrow 8^- f(x) =   
  
  Solution
at f(7) there is hole so f(7) = DNE
limit x tends to 8- f(x) =5
limit x tends to 8+ f(x) =5
limit x tends to 8 f(x) =5
