Transcribed Image Text:**Problem 3: Optimization on a Line Segment**
*Objective:* Find a point \( P \) on the segment \( AB \) that minimizes the length \( XP + PY \).
*Hint:* Denote \( AP = x \) and express \( XP + PY \) as a function of \( x \).
**Diagram Explanation:**
- The line segment \( AB \) has a total length of 16 units.
- A perpendicular line at point \( A \) extends to point \( X \), located 2 units above \( A \).
- Another perpendicular line at point \( B \) extends to point \( Y \), located 6 units above \( B \).
The task is to determine point \( P \) along \( AB \) such that the total distance from \( X \) to \( P \) to \( Y \) is minimized.
