The given function is \( k(x) = 7x - 4 \). Let's evaluate the function at the specified values:

### A) Evaluate \( k(0) \)
\[ k(0) = 7(0) - 4 = -4 \]

### B) Evaluate \( k(2) \)
\[ k(2) = 7(2) - 4 = 14 - 4 = 10 \]

### C) Evaluate \( k(-2) \)
\[ k(-2) = 7(-2) - 4 = -14 - 4 = -18 \]

### D) Evaluate \( k(x + 1) \)
\[ k(x + 1) = 7(x + 1) - 4 = 7x + 7 - 4 = 7x + 3 \]

### E) Evaluate \( k(-x) \)
\[ k(-x) = 7(-x) - 4 = -7x - 4 \]

Here are the results:

- \( k(0) = -4 \)
- \( k(2) = 10 \)
- \( k(-2) = -18 \)
- \( k(x + 1) = 7x + 3 \)
- \( k(-x) = -7x - 4 \)

If you need further details or have any questions, feel free to ask! Here are some related questions you might consider:

1. What would be the graph of the function \( k(x) \)?
2. How does modifying the coefficient of \( x \) affect the graph of \( k(x) \)?
3. What are the intercepts of the function \( k(x) \)?
4. What happens to the function values as \( x \) becomes very large or very small?
5. Can you determine the inverse of the function \( k(x) \)?

**Tip:** Always double-check your work, especially in substitutions, to ensure accuracy in evaluations and calculations.

Given the function k(x) = 7x - 4, evaluate the following expressions: k(0), k(2), k(-2), k(x + 1), k(-x).
