To analyze the transformation from \( g(x) \) to \( h(x) \), we first write out both functions clearly:

  1. \( g(x) = -4\sqrt{x+1} + 3.5 \)
  2. \( h(x) = -4\sqrt{x+1} - 4.5 \)

Now, we can compare the two functions:

  • The main difference between \( g(x) \) and \( h(x) \) is in the constant term.

This can be expressed as:

  • \( g(x) \) has a constant term of \( +3.5 \).
  • \( h(x) \) has a constant term of \( -4.5 \).

To find the vertical translation, we can calculate the difference in the constant terms:

\[ k = -4.5 - 3.5 = -8 \]

This means \( h(x) \) is obtained by taking \( g(x) \) and translating it downward by 8 units.

Thus, the correct response is:

vertical translation down 8 units.
