Question Analysis
This question tests the student's ability to interpret a graphical representation of an inequality and write it in symbolic form.

Key Concept Explanation
Inequalities are mathematical statements that use symbols such as , , , and to compare two expressions. The number line is a visual representation where each point corresponds to a number, and the shaded region indicates the solution set.

Step-by-step Solution
1. Observe the number line and identify the boundary point, which is 4.
2. Determine if the boundary point is included or excluded. An open circle at 4 indicates that 4 is not included.
3. Identify the direction of the shading. Shading to the left of 4 indicates all numbers less than 4...
