1. **State the problem:** We are given a graph of a function $f$ and need to find the values $f(-14)$, $f(0)$, and $f(-7)$ from the graph.
2. **Analyze the graph:** The graph is a straight line that crosses the y-axis at about $y=4$ and the x-axis at about $x=4$. This suggests the function is linear.
3. **Find the equation of the line:** The line passes through points approximately $(-14,10)$ and $(4,0)$.
4. **Calculate the slope $m$:**
$$m = \frac{0 - 10}{4 - (-14)} = \frac{-10}{18} = -\frac{5}{9}$$
5. **Use point-slope form to find $f(x)$:**
Using point $(4,0)$:
$$y - 0 = -\frac{5}{9}(x - 4)$$
$$f(x) = -\frac{5}{9}x + \frac{20}{9}$$
6. **Calculate $f(-14)$:**
$$f(-14) = -\frac{5}{9}(-14) + \frac{20}{9} = \frac{70}{9} + \frac{20}{9} = \frac{90}{9} = 10$$
7. **Calculate $f(0)$:**
$$f(0) = -\frac{5}{9}(0) + \frac{20}{9} = \frac{20}{9} \approx 2.22$$
8. **Calculate $f(-7)$:**
$$f(-7) = -\frac{5}{9}(-7) + \frac{20}{9} = \frac{35}{9} + \frac{20}{9} = \frac{55}{9} \approx 6.11$$
**Final answers:**
- $f(-14) = 10$
- $f(0) = \frac{20}{9} \approx 2.22$
- $f(-7) = \frac{55}{9} \approx 6.11$
