To find $(f - g)(1)$, we need to first determine the expression for $f(x) - g(x)$ and then evaluate it at $x = 1$.

1. Find $f(x) - g(x)$:

   $f(x) = 2x + 4$ $g(x) = x + 3$ Subtracting $g(x)$ from $f(x)$:

   $(f - g)(x) = f(x) - g(x) = (2x + 4) - (x + 3)$

   Simplify the expression:

   $(f - g)(x) = 2x + 4 - x - 3 = x + 1$

2. Evaluate $(f - g)(1)$:

   Substitute $x = 1$ into the simplified expression:

   $(f - g)(1) = 1 + 1 = 2$

So, $(f - g)(1) = 2$.

Here are 5 related questions you might find interesting:

1. What is $(f + g)(1)$ using the same functions $f(x)$ and $g(x)$?
2. How would you find $(f \cdot g)(x)$ for the given functions?
3. What is the derivative of $(f - g)(x)$?
4. How would you determine $(f \circ g)(x)$ for these functions?
5. If $h(x) = f(x) - g(x)$, what is the value of $h(2)$?

Tip: When combining functions, always simplify the expressions before evaluating them at a specific value.
