<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

3.6

now the second decimal place:

3.61

does it remain unchanged? No! the number AFTER is is 5 or bigger (it's 7), so we need to round it up. the answer is this:

3.62
