Question

PLEASE HELP ME I DON'T KNOW HOW TO EXPLAIN IT IS A FUNCTION Determine if (−6ˏ−2)ˏ(−2ˏ6)ˏ(0ˏ3)ˏ(3ˏ5) is a function EXPLAIN.

Answer 1

a 'function' means that you can't have one x value going to two different y values.

(−6ˏ−2)ˏ -6 goes to -2
(−2ˏ6)ˏ -2 goes to 6
(0ˏ3)ˏ 0 goes to 3
(3ˏ5) 3 goes to 5

no single x input goes to two different y values, so this is a function.


Example of set that IS NOT A FUNCTION:
(2, 3)
(2, 4)
(3, 6)
do you see how we have x=2 and it has a y=3 and a y=4. this is not a function becuase one x value goes to two different y values.
