Question

PLEASE PLEASE PLEASE HELP!!!!! 95 points!!!
Alicia is writing the program for a video game. For one part of the game, she uses the rule (x, y) → (x – 3, y + 2) to move points on the screen

a. What output does the rule give when the input is (-2, 0)? Show your work. (2 points)

b. What output does the rule give when the input is (3, -4)? Show your work. (2 points)

c. Is the rule a function? (1 point) Explain why it is or why it is not. (2 points)

Answer 1

The "rule" being described here is nothing more than the input/output of a mathematical function.

For every input 'x' value supplied, you only need to subtract three to it. For every input 'y' value, you only need to add four to it.

Example: I'll use variable 'm' to represent this function. Variable 'p' will represent the current input point.

m(p) = p[x - 3, y + 4] = p[-7 - 3, 0 + 4] = p[-10, 4]. 'p[]" is just the point.

I tried my best hope that help!

Answer 2

a. (-5,2)

insert -2 as x and 0 as y so you get something like (-2-3,0+2). negative two minus three is negative five. zero pls two is two.

b. do the same.
the answer is (0,-2
just solve (3-3,-4+2)

c. this is a function because each time you input an x or y coordinate, there is only one output.
