Question: Use the graph of $y = f(x)$ to graph the function
$g(x) = f(x) - 2$.
$y = f(x)$
Choose the correct graph of $g$ below.
A. position_hint \in \{top-right\}: horizontal blue line segment from $x = -2$ to $x = 2$ at $y = 4$.
B. position_hint \in \{top-right\}: horizontal blue line segment from $x = -2$ to $x = 2$ at $y = 3$.
C. position_hint \in \{bottom-right\}: horizontal blue line segment from $x = -2$ to $x = 2$ at $y = 1$.
D. position_hint \in \{bottom-right\}: horizontal blue line segment from $x = -2$ to $x = 2$ at $y = 0$.
1. **State the problem:** We are given a function $y = f(x)$ and asked to graph $g(x) = f(x) - 2$ using the graph of $f(x)$.
2. **Understand the transformation:** The function $g(x) = f(x) - 2$ represents a vertical shift of the graph of $f(x)$ downward by 2 units.
3. **Apply the transformation:** If the original graph $f(x)$ has a horizontal line segment from $x = -2$ to $x = 2$ at some height $y = h$, then the graph of $g(x)$ will have the same segment shifted down by 2 units, i.e., at $y = h - 2$.
4. **Identify the original height:** From the options, the original $f(x)$ segment is at $y = 3$ or $y = 4$ or $y = 1$ or $y = 0$. Since $g(x) = f(x) - 2$, the correct graph of $g$ should be the original graph shifted down by 2.
5. **Check each option:**
- If $f(x)$ is at $y = 4$, then $g(x)$ is at $4 - 2 = 2$ (not listed).
- If $f(x)$ is at $y = 3$, then $g(x)$ is at $3 - 2 = 1$ (option C).
- If $f(x)$ is at $y = 1$, then $g(x)$ is at $1 - 2 = -1$ (not listed).
- If $f(x)$ is at $y = 0$, then $g(x)$ is at $0 - 2 = -2$ (not listed).
6. **Conclusion:** The correct graph of $g$ is option C: a horizontal blue line segment from $x = -2$ to $x = 2$ at $y = 1$.
**Final answer:** Option C.
