Answer:

  • reflection over the x-axis
  • translate right 2 units
  • translate down 3 units

Explanation:

Horizontal translation of the graph of a function is accomplished by replacing x with (x-h) for translation h units to the right. Vertical translation of the graph is accomplished by adding the amount of translation to the function value: f(x)+k translates the graph k units upward.

Reflection of a function over the x-axis is accomplished by changing the sign of every function value: -f(x).

Application

We observe that f(x) has been transformed by ...

  • multiplying by -1 to get -f(x)
  • replacing x with (x -2) to get -f(x -2)
  • adding -3 to the function value to get -f(x -2) -3

The effect of these transformations is (correspondingly) ...

  • reflection over the x-axis
  • translate right 2 units
  • translate down 3 units

__

The attached graph shows a function f(x) (red) and the transformed function (blue).
