We are given the functions \( f(x) \) and \( g(x) \) with certain values at \( x = 4 \), and we're tasked with finding \( h'(4) \) for \( h(x) = \frac{f(x)}{g(x)} \).

### Step 1: Use the Quotient Rule for Derivatives
The derivative of \( h(x) = \frac{f(x)}{g(x)} \) is given by the quotient rule:

\[
h'(x) = \frac{f'(x)g(x) - f(x)g'(x)}{(g(x))^2}
\]

### Step 2: Plug in the values at \( x = 4 \)

We are given:
- \( f(4) = 2 \)
- \( g(4) = 5 \)
- \( f'(4) = 6 \)
- \( g'(4) = -3 \)

Substitute these values into the quotient rule formula:

\[
h'(4) = \frac{f'(4)g(4) - f(4)g'(4)}{(g(4))^2}
\]

\[
h'(4) = \frac{6 \times 5 - 2 \times (-3)}{5^2}
\]

### Step 3: Simplify the expression

\[
h'(4) = \frac{30 + 6}{25} = \frac{36}{25}
\]

This simplifies to:

\[
h'(4) = 1.44
\]

### Final Answer: 
The value of \( h'(4) \) is \( 1.44 \) (exact decimal value).

2. How do you apply the product rule in differentiation?
3. Can the quotient rule be used for three functions?
4. What is the geometric interpretation of \( h'(4) \)?
5. How would the solution change if \( g(4) \) were 0?

**Tip:** Always verify the conditions (such as non-zero denominator) before applying the quotient rule to avoid undefined expressions.

Suppose that f(4) = 2, g(4) = 5, f'(4) = 6, g'(4) = -3. Let h(x) = f(x) / g(x). Evaluate h'(4). Give answer as an exact decimal value.
