Question 2 (1 point) Which option expresses "all values less than 100 " in interval notation? \( \{x \mid x<100\} \) \( (-\infty, 100) \) \( (-\infty, 100] \) \( (100, \infty) \)

Interval notation is a concise way of expressing a range of values. The option \( (-\infty, 100) \) accurately conveys "all values less than 100" because it includes all numbers extending negatively to infinity up to, but not including, 100 itself. In contrast, the option \( (-\infty, 100] \) suggests that 100 is included in the interval, which is incorrect for the requirement of "less than 100." It’s essential to understand the difference between open and closed intervals when working with such notations!
