Write the set $\{x \mid x<4\}$ using interval notation, then graph the set on a number line.
Choose the correct interval notation for the set. $[4, \infty)$ $(-\infty, 4)$ $(4, \infty)$ $(-\infty, 4]$ Choose the correct graph below. A. B. C. D.

Studdy Solution
Identify the correct graph for the interval $(- \infty, 4)$.
- The graph should have an open circle at 4, indicating that 4 is not included. - The line should extend leftwards, indicating all numbers less than 4.
Based on the image descriptions, the correct graph is:
- A: A line with an open circle at 4 extending leftwards.
Therefore, the correct graph is option A.
The correct interval notation is $(- \infty, 4)$ and the correct graph is option A.
