Answer :
All real numbers y that are less than 4: y < 4
All real numbers y that are greater than 9: y > 9
Therefore, y < 4 or y > 9
All real numbers y that are greater than 9: y > 9
Therefore, y < 4 or y > 9
Answer:
All real numbers y that are less than 4: y < 4
All real numbers y that are greater than 9: y > 9
Therefore, y < 4 or y > 9
