1. The range of the following relation: R: {(3, -5), (1, 2), (-1, -4), (-1, 2)} is?

2. The domain of the following relation: R: {(3, -2), (1, 2), (-1, -4), (-1, 2)} is ?

Answer 1

Range is all of the y values, domain is all of the x values.

so range for the first one, or all of the y values is

[-5,2,-4]

any idea for the second one?

Answer 2

no i hve no idea :(

Answer 3

x values is the first number in a coordinate. so in for example (5,2)

5 is the x value.

now list all the x values you see in the second problem

Answer 4

{-4, -2, 2, 2}?

Answer 5

No.

{3,1,-1}

R: {(3, -2), (1, 2), (-1, -4), (-1, 2)}

-1 is listed twice but you only have to include it once

Answer 6

oh ok i get it
