Question
**Problem:**

Given the function \( g(x) = 9 - x^2 \), evaluate \(\frac{g(x + h) - g(x)}{h}\), \( h \neq 0 \).

**Explanation:**

This problem asks you to find the difference quotient for the given function. The difference quotient is a fundamental concept in calculus that represents the slope of the secant line between two points on the graph of a function, often used as a step toward finding the derivative.

1. **Function Information:**
   - The function is \( g(x) = 9 - x^2 \).

2. **Difference Quotient:**
   - It is expressed as \(\frac{g(x + h) - g(x)}{h}\).
   - This formula is used to calculate the average rate of change of the function over a small interval \( h \).

3. **Objective:**
   - Evaluate the expression to find how the function changes as \( x \) changes by a small amount \( h \), assuming \( h \neq 0 \).

This exercise helps illustrate how derivatives are calculated as \( h \) approaches zero.
