To find $(f - g)(0)$, you need to evaluate the difference between the functions $f(x)$ and $g(x)$ at $x = 0$. Here's how you can do it:

1. Evaluate $f(0)$:

   • Look at the graph of $f(x)$ (the red curve) and find the value of $f(0)$.
   • From the graph, at $x = 0$, $f(0) = 1$.

2. Evaluate $g(0)$:

   • Look at the graph of $g(x)$ (the blue line) and find the value of $g(0)$.
   • From the graph, at $x = 0$, $g(0) = 2$.

3. Calculate $(f - g)(0)$: $(f - g)(0) = f(0) - g(0) = 1 - 2 = -1$

So, $(f - g)(0) = -1$.

Would you like any further explanation or have any additional questions?

Here are some related questions to deepen your understanding:

1. How would you interpret the graph of the function $f(x) - g(x)$?
2. What is the domain of the difference of two functions?
3. How do you determine the range of $f(x) - g(x)$?
4. Can you express $(f + g)(x)$ using the same steps we used here?
5. How does the vertical translation of a function affect its graph?

Tip: Always carefully observe the signs when subtracting functions, as it can significantly affect the outcome.
