**F(x)=|x-3|-2; vertical stretch by a factor of 3**

**Answer:**

The question asks for a vertical stretch. The form is of a(x-h)+k , where k is the vertical translation. So, a stretch of 3 simply means to multiply your k value (-2) by 3. This will give you the new vertical stretch. You should be able to take it from here. Good Luck!
