Question

rotations as functions quick check
the rotation function mapping for a 90 - degree clockwise rotation about the origin is equivalent to which other transformation mapping? (1 point)
a translation
a 270 degrees counterclockwise rotation
a dilation with a scale factor of $\frac{1}{4}$
a reflection over the line $y = x$

Explanation:

A 90 - degree clockwise rotation about the origin and a 270 - degree counterclockwise rotation about the origin both change the coordinates of a point in the same way. A translation moves a figure without rotating it, a dilation changes its size, and a reflection over the line $y = x$ is a different transformation.

Answer:

B. a 270 degrees counterclockwise rotation
