### 4.4 Exercise Set

**Find the area under the graph of f over \([1, 5]\).**

1. \( f(x) = \begin{cases} 
x + 5, & \text{for } x \leq 4 \\ 
11 - \frac{1}{2}x, & \text{for } x > 4 
\end{cases} \)

2. \( f(x) = \begin{cases} 
2x + 1, & \text{for } x \leq 3 \\ 
10 - x, & \text{for } x > 3 
\end{cases} \)

**Find the area under the graph of g over \([-2, 3]\).**

3. \( g(x) = \begin{cases} 
-x^2 + 5, & \text{for } x \leq 0 \\ 
x + 5, & \text{for } x > 0 
\end{cases} \)

4. \( g(x) = \begin{cases} 
x^2 + 4, & \text{for } x \leq 0 \\ 
4 - x, & \text{for } x > 0 
\end{cases} \)

**Find the area under the graph of f over \([-6, 4]\).**

5. \( f(x) = \begin{cases} 
-x - 1, & \text{for } x < -1 \\ 
-x^2 + 4x + 5, & \text{for } x \geq -1 
\end{cases} \)

6. \( f(x) = \begin{cases} 
-x^2 - 6x + 8, & \text{for } x < 1 \\ 
2x - 1, & \text{for } x \geq 1 
\end{cases} \)

**Find the area represented by each definite integral.**

7. \( \int_{-3}^{4} |x^3| \, dx \)

8. \( \int_{0}^{2} |x^3 - 1| \, dx \)

9. \( \int_{0}^{4} |x - 3| \, dx \)
