Answer 1

In the context of vertical dilations or compressions of functions, the factor \( k \) represents how the function has been changed compared to the original function.

The original function is \( y = |x + 6| \). The dilated function is given as \( y = \frac{1}{2} |x + 6| \).

To identify the factor \( k \) for the vertical compression, we compare the two functions:

- The original function has a coefficient of \( 1 \) in front of \( |x + 6| \) (which can be considered as \( k = 1 \)).
- The dilated function has a coefficient of \( \frac{1}{2} \) in front of \( |x + 6| \).

Since the coefficient is less than \( 1 \), it indicates a vertical compression. The factor \( k \) is simply the coefficient in front of the absolute value in the dilated function.

Thus, we have:
\[
k = \frac{1}{2}
\]

So the answer is:
\[
\boxed{\frac{1}{2}}
\]
