Question

identify the domain and range of the relation. ((-9,2),(-4,2), (3,2), (9,2)

Answer 1

The domain is simply the list of all possible inputs, or x values


so you just list all the x coordinates and toss out any duplicates. Make sure to surround the list by curly braces

Answer 2

similarly, the range is the set of outputs or y values

to form the range, list the y coordinates, toss out the duplicates and surround the list with curly braces

Answer 3

I am so confused right now. so confused

Answer 4

here is an example:

let's say we're given the points (1,2),(7,5),(10,4)

The domain would be {1,7,10}
Notice how I listed the x coordinates

The range would be {2,5,4}
Notice how I listed the y coordinates

Answer 5

let me know if that example helps you find the answer
