Question

should x < 7 be an open or closed point?

Answer 1

In the context of inequalities, the expression \( x < 7 \) indicates that \( x \) can take any value less than 7 but cannot equal 7 itself. Therefore, when graphing this inequality on a number line, you would represent 7 with an **open point** to show that 7 is not included in the solution set.

In summary:
- For \( x < 7 \): **Open point at 7** (indicating that 7 is not included).
