Answer:

  • The Expression will be defined if the denominator is not equal to 0 since any number divided by 0 is undefined.
  • Therfore our main priority here is to check the denominator only because it's the only part that can make the expression undefined
  • the expression will be defined for all real numbers (a) BUT 3+a must not equal to 0 therfore (a) can be all real numbers but must never be equal to -3

Explanation:


  • a \: is \: an \: element \: of \: all \: real \: numbers \: but \: not \: not \: equal \: to \: -3
  • HOPE THIS HELPS!
