1. **State the problem:** We are given a piecewise function:
$$f(x) = \begin{cases} 2x + 9 & \text{for } x < -3 \\ 2x - 2 & \text{for } x > 4 \end{cases}$$
2. **Understand the function:** This function has two linear pieces defined on two separate intervals: one for $x < -3$ and one for $x > 4$. There is no definition for $-3 \leq x \leq 4$.
3. **Graphing each piece:**
- For $x < -3$, the function is $f(x) = 2x + 9$. This is a line with slope 2 and y-intercept 9.
- For $x > 4$, the function is $f(x) = 2x - 2$. This is a line with slope 2 and y-intercept -2.
4. **Evaluate key points:**
- At $x = -3$, the first piece is not defined (strictly less than -3), but we can find the limit from the left:
$$f(-3^-) = 2(-3) + 9 = -6 + 9 = 3$$
- At $x = 4$, the second piece is defined for $x > 4$, so not at 4 exactly, but the limit from the right is:
$$f(4^+) = 2(4) - 2 = 8 - 2 = 6$$
5. **Summary:** The graph consists of two separate line segments:
- Line segment $y = 2x + 9$ for $x < -3$.
- Line segment $y = 2x - 2$ for $x > 4$.
There is a gap between $x = -3$ and $x = 4$ where the function is not defined.
**Final answer:** The piecewise function is correctly defined as above with two linear pieces and a gap in between.
