Let's solve the problem step by step by analyzing the graph and the given questions:

(a) Find $f(1)$:

To find $f(1)$, look at the graph where $x = 1$ and find the corresponding $y$-value. On the graph, when $x = 1$, the $y$-value is approximately 3. Hence:

$f(1) = 3$

(b) Find one value of $x$ for which $f(x) = 0$:

We are looking for the $x$-value where the graph intersects the $x$-axis, which is when $f(x) = 0$. From the graph, the function intersects the $x$-axis at $x = -3$.

Thus:

$x = -3$

Final answers:

• $f(1) = 3$
• One value of $x$ for which $f(x) = 0$ is $x = -3$.

Let me know if you need any more details!

Here are 5 related questions for further practice:

1. What is $f(0)$ based on the graph?
2. Find the slope of the line represented by the graph.
3. How would you find the $y$-intercept of the function?
4. What is the domain and range of this function?
5. How can you express this linear function algebraically?

Tip: To find where a function equals zero (i.e., its roots), always check where it crosses the x-axis.
