We are asked to find $f(-1)$ based on the graph of the function $f(x)$.

To find $f(-1)$:

1. Look at the x-coordinate of -1 on the graph (along the horizontal axis).
2. Move vertically from $x = -1$ until you hit the graph of the function.
3. The y-coordinate at that point will be the value of $f(-1)$.

From the graph:

• When $x = -1$, the corresponding $y$-coordinate is 2. Thus, $f(-1) = 2$.

Let me know if you need further clarification!

Here are five related questions to consider:

1. How can you determine the slope of this linear function from the graph?
2. What is the equation of the line represented by $f(x)$?
3. How would you calculate $f(2)$ using the same method?
4. Can you predict $f(x)$ for values outside the graph, like $f(-10)$?
5. How would you determine the x-intercept from this graph?

Tip: To find values of a function from a graph, always match the x-value to its corresponding y-value on the curve or line.
