### Question

Alicia is writing the program for a video game.  For one part of the game she uses the rule (x, y) → (x - 3,y + 4) to move points on the screen.

(a)  What output does the rule give when the input is (-6, 0)?

(b)  What output does the rule give when the input is (3, -4)?

(c)  Is the rule a function? Explain why it is or why it is not.

### Solution

(a)  Input (-6, 0) → Output (-6 - 3, 0 + 4) = (-9, 4)

(b)  Input (3, -4) → Output (3 - 3, -4 + 4) = (0, 0)

(c)  The rule is a one-to-one function as each value in the range (y-values) corresponds to exactly one value in the domain (x-values).
