To determine the order of transformations from \( f(x) = x^3 \) to \( f(-x + 2) + 4 \), we'll analyze the transformations step by step.

  1. Start with the original function: \( f(x) = x^3 \).

  2. Horizontal reflection: The transformation \( -x \) reflects the graph across the y-axis. Therefore, \( f(-x) = (-x)^3 = -x^3 \).

  3. Horizontal translation: The transformation \( -x + 2 \) can be rewritten as \( -(x - 2) \), which indicates a horizontal translation to the right by 2 units. Thus, \( f(-x + 2) \) can be computed as \( f(- (x - 2)) \) which becomes \( -(x-2)^3 \).

  4. Vertical translation: Finally, adding 4 to the function shifts the graph up by 4 units. Therefore, \( f(-x + 2) + 4 \) translates vertically, giving us \( -(x - 2)^3 + 4 \).

Now, summarizing the transformations:

  1. Horizontal reflection
  2. Horizontal translation (to the right by 2)
  3. Vertical translation (up by 4)

Given the order of transformations, the correct option is:

horizontal reflection, horizontal translation, vertical translation.
