Question

graph the interval represented in interval notation on the number line. (-∞,11) answer attempt 1 out of 2 number line: -12 -10 -8 -6 -4 -2 0 2 4 6 8 10 12

Explanation:

Step1: Understand interval notation

The interval $(-\infty, 11)$ represents all real - numbers less than 11. The symbol $-\infty$ indicates that the interval extends infinitely to the left, and the parenthesis means 11 is not included.

Step2: Graph on number line

On the number line, find the point 11. Draw an open circle at 11 (since 11 is not in the interval) and draw an arrow to the left to represent all the numbers less than 11.

Answer:

Draw an open circle at 11 on the number line and an arrow pointing to the left.
