a figure is rotated. 90° counterclockwise about the organ which of the following function mapping was applied. Enter the number of the correct option.

Answer 1

To determine the mapping function for a 90° counterclockwise rotation about the origin, we can use the following transformation for a point $(x,y)$:

$$(x,y)\to (-y,x)$$

This means that the new coordinates after the transformation will be $(-y,x)$.

If you have specific options listed, please provide them, and I can help you identify the correct option based on this transformation.
