To analyze the transformation that converts the graph of \( f(x) = -3|x - 9| - 10 \) into \( g(x) = -3|x - 9| - 3 \), we can compare the two equations.

  1. Original function: \[ f(x) = -3|x - 9| - 10 \]

  2. Transformed function: \[ g(x) = -3|x - 9| - 3 \]

The key differences between these two functions lie in the constant terms.

  • In \( f(x) \), the constant term is \(-10\).
  • In \( g(x) \), the constant term is \(-3\).

To find the vertical transformation, we note that the change from \(-10\) to \(-3\) means:

\[ -3 - (-10) = -3 + 10 = 7 \]

This indicates that \( g(x) \) is attained by shifting the graph of \( f(x) \) upward by 7 units.

Thus, the correct transformation is translates it 7 units up.
