Question
**Problem 2: Inequality to Interval Notation and Graph**

Rewrite each of the following inequalities in interval notation and graph them on a real number line.

**a) \( 4 < x \)**

*Interval Notation*: \((4, \infty)\)

**b) \( -2 < x < 7 \) or \( x > 11 \)**

*Interval Notation*: \((-2, 7) \cup (11, \infty)\)

**Graph Explanation:**

1. For part (a), the graph would be a number line with an open circle at 4 and an arrow pointing to the right, indicating all numbers greater than 4 extending to infinity.
2. For part (b), the graph would include:
   - An open interval between -2 and 7, shown by open circles at both -2 and 7, indicating all numbers between -2 and 7.
   - An open circle at 11 with an arrow pointing to the right, representing all numbers greater than 11.
