Hi there!

I believe your answer is:
A vertical shift down one unit.

Here’s why:
- A chart showing the rules of function transformations are shown.
- The equation shown is the parent function of '2x' that is shifted 1 unit down.
- If the number was inside the x [like (x - 1)] it would be a horizontal transformation. Since it's outside we would consider it to be a vertical shift.

Hope this helps you. I apologize if it’s incorrect.
