Math Problem Statement

When the graph of y = |x| was shifted in the video, where did the point (2,0) move to?

Solution

The problem asks about the transformation of the graph y=xy = |x| when it becomes y=x2y = |x - 2|, and specifically where the point (2,0)(2,0) moves under this transformation.

Explanation:

The equation y=x2y = |x - 2| represents a horizontal shift of the graph y=xy = |x| to the right by 2 units. Here’s how the transformation works:

  1. Any point (x,y)(x, y) on y=xy = |x| will move to the point (x+2,y)(x + 2, y) on y=x2y = |x - 2|.
  2. The point (2,0)(2, 0) is already on the vertex of y=x2y = |x - 2|, because substituting x=2x = 2 into y=x2y = |x - 2| yields y=0y = 0. Therefore, this point does not move.

Conclusion:

The correct answer is D. It did not move.
