Question

This means to move a graph vertically and/or horizontally around the coordinate plane.

Example: Shifting a graph to the left is a horizontal translation

Answer 1

Translation of graphs is the correct answer

Answer 2

To move a graph vertically and/or horizontally around the coordinate plane is called shifting or translation.

Shifting is simply moving the graph. Horizontal shift would be moving/shifting the graph to left or right. Vertical shift would be moving/shifting the graph to up or down.
There are another transformation methods that involve a more complex equation than shifting like mirroring or rotating.
