Which numbers do you want? Also, you have to do the same thing on the other side if you do it on one.
Answer:
According to the 180°-rotation rule, you take the OPPOSITE of both the x-coordinate and y-coordinate:
180°: [<em>x</em>, <em>y</em>] → [<em>-x</em>, <em>-y</em>]

Rule: second differences are 2.
Selection C is appropriate.
_____
First differences are the sequence of differences of the given numbers:
.. 3 -8 = -5
.. 0 -3 = -3
.. -1 -0 = -1
.. 0 -(-1) = 1
Second differences are the sequence of differences of these:
.. -3 -(-5) = 2
.. -1 -(-3) = 2
.. 1 -(-1) = 2
All of these are 2, so the sequence can be described by a *second* order polynomial (because *second* differences are a non-zero constant).
