<h3>
Answer:</h3>
f((x, y)) = (-y, -x)
<h3>
Step-by-step explanation:</h3>
Rotation 90° CCW about the origin is the mapping ...
... (x, y) ⇒ (-y, x)
Reflection across the x-axis is the mapping ...
... (x, y) ⇒ (x, -y)
Together, these do the following mapping:
... (x, y) ⇒ (-y, -x) . . . . . . . equivalent to a reflection across y = -x
Expressed as a function, this might be written ...
... f((x, y)) = (-y, -x) . . . . . . . the ordered pair argument becomes a new ordered pair
