Answer:
Every input can have only one output. But an output can have multiple inputs. Basically an x coordinate can have the same y coordinate as another ordered pair but not the same x coordinate. This is why d) does not represent a function.
Step-by-step explanation:
(4,-2)
(4,2)
4 is mentioned twice and every input( x value) can have only one output ( y-value)
If this is supposed to be

Then this can simply be reduced to

by the double angle formula for cosine
What you do is multiply x and y by 4 so the new be point is (-36,24)
The rotation that that translates AWXY to AW'X'Y' is a 45° anticlockwise rotation. See the attached image for details.
<h3>What is a rotation in math?</h3>
Rotation in math refers to the change in the angle of a geometric shape around a central axis on a point on the geometric plane such that it's original coordinates are modified but it's size or shape.
Hence, it is correct to state that The rotation that that translates AWXY to AW'X'Y' is a 45° anticlockwise rotation.
