How do I sketch the function? 

### Piecewise Function and Its Graph

In this example, we are given a piecewise function \( f(x) \) defined as follows:

\[
f(x) =
\begin{cases} 
-x - 6 & \text{if } x \leq -3 \\
-3 & \text{if } -3 < x \leq 4 \\
1.5 - 7 & \text{if } x > 4 
\end{cases}
\]

We are required to sketch the graph of this piecewise function based on the given conditions.

### Analysis of Each Piece

1. **For \( x \leq -3 \):** The function is \( f(x) = -x - 6 \). 
   - This is a linear function with a negative slope.
   - As \( x \) decreases, \( f(x) \) increases according to the equation.
   
2. **For \( -3 < x \leq 4 \):** The function is \( f(x) = -3 \).
   - This is a constant function, meaning for all \( x \) in this interval, \( f(x) \) is always -3.
   
3. **For \( x > 4 \):** The function is \( f(x) = 1.5 - 7 \).
   - This simplifies to \( f(x) = -5.5 \), indicating another constant function where \( f(x) \) is always -5.5 for \( x \) greater than 4.

### Graph Explanation

The provided graph paper has both horizontal and vertical axes marked with grid lines. Here's how to sketch the graph based on the piecewise function:

1. **For the interval \( x \leq -3 \):**
   - Plot the line \( f(x) = -x - 6 \). 
   - For example, when \( x = -3 \), \( f(x) = -(-3) - 6 = 3 - 6 = -3 \).
   - Extend the line with that slope to the left of \( x = -3 \).

2. **For the interval \( -3 < x \leq 4 \):**
   - Draw a horizontal line at \( f(x) = -3 \)
   - This extends from just greater than \( x = -3 \) to \( x = 4 \
