Question

graph the set {x | x < 2} on the number line. then, write the set using interval notation.

Explanation:

Step1: Graph on number - line

Draw an open circle at 2 (since x < 2, 2 is not included) and shade the line to the left of 2.

Step2: Write in interval notation

The set of all real numbers less than 2 is written as $(-\infty,2)$.

Answer:

On the number - line: Open circle at 2, shade to the left. Interval notation: $(-\infty,2)$
