Graph the given function and find all values of x where the
     Graph the given function, and find all values of x where the function is discontinuous.  Choose the correct graph of the function.  Determine all the values of x where the function is discontinuous.  The function is continuous for all values of x.  The function is discontinuous for x = 3.  The function is discontinuous for x = - 4.  The function is discontinuous for x = - 4 and x = 3.   
  
  Solution
option B
