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
