Click to expand... I'll show you example of other problems. a. the set of all real numbers that strictly less than -8 In this case, -8 is not included in the set. So the interval notation would be (-inf., -8) b. the set of all real numbers that less than or equal to -8 In this case, -8 is included in the set. So the interval notation would be (-inf., -8] ...... notice the type of parenthesis changed.
