Answer:

  • reflection over the x-axis
  • translation down 8 units

Step-by-step explanation:

g(x) = -f(x) -8

The function is multiplied by -1, which reflects it over the x-axis. -8 is added to each function value, which translates it down 8 units.

The transformations are reflection over y=0 and translation down 8 units.

_____

The original flattened-S shaped curve is reversed top-to-bottom and is moved down. Attached is the original (red) and the transformed function (blue).

Because this is an odd function, reversing it top-to-bottom has the same appearance as reversing it left-to-right.
