Answer: D, neither A nor B
Step-by-step explanation: In a function, the x (the input) cannot repeat in the given set of ordered pairs. In Set A, 2 repeats in the third and fourth ordered pairs. In Set B, 9 repeats in the third and fourth ordered pairs as well.
C. (-1, -2) would be your answer
That transformation is just a translation (x-2, y-4) from point (1,2)
The answer is <em>x</em>=5.
Solve for <em>x</em>. (The question mark should be <em>x</em>.)
