The problem in the image asks for the value of the limit:

$\lim_{x \to 2} (2x - 8)$

To solve this, we can directly substitute $x = 2$ into the expression $2x - 8$:

$2(2) - 8 = 4 - 8 = -4$

Therefore, the value of the limit is $-4$.

The correct answer is D.

Would you like more details or have any other questions?

Here are five follow-up questions:

1. What is the definition of a limit?
2. How can you compute limits for more complex functions?
3. What happens if you substitute into a limit and get an indeterminate form?
4. Can limits be evaluated at points where the function is undefined?
5. What are the different types of limits (one-sided, two-sided)?

Tip: For simple linear functions like $2x - 8$, limits can usually be found by direct substitution unless the function behaves differently near the point of interest.
