Question
**Title: Elastic Demand Analysis**

**Problem Statement:**
Find the values of \( p \) where demand is elastic.

**Equation:**
\[ x = \sqrt{324 - 2p} \]

**Context and Explanation:**
In this problem, \( x \) represents the quantity demanded, which is a function of the price \( p \). To determine where demand is elastic, we need to understand the relationship between changes in price and changes in quantity demanded.

**Detailed Analysis:**
To find where the demand is elastic, we may need to calculate the elasticity of demand using the given equation. The elasticity of demand can be analyzed by differentiating the demand function with respect to price and applying the elasticity formula:

\[ E = \left( \frac{dx}{dp} \right) \left( \frac{p}{x} \right) \]

The demand is considered elastic when the absolute value of \( E \) is greater than 1.
