3) [2; t): This interval represents all real numbers greater than or equal to 2 and less than t. It includes 2.

4) (-5; 5): This interval represents all real numbers greater than -5 and less than 5. It does not include -5 or 5.

5) (-2; 9): This interval represents all real numbers greater than -2 and less than 9. It does not include -2 or 9.

6) [0; +∞): This interval represents all real numbers greater than or equal to 0. It includes 0 and extends to positive infinity.

7) 42: This is a single number and not an interval. It represents the number 42.
