Question

1.Find the domain of the following relation r.
r = {(4, -5), (-6, 2), (-3, -8)}

2. Find the domain of the following relation r.
r = {(1, 3), (5, 1), (0, 8), (-5, -9)}

3. Find the range of the following relation r.
r = {(-1, 9), (-2, -6), (7, -1), (-12, 4), (5, -3)}

4.Find the range of the following relation r.
r = {(-7, 0), (-2, -2), (1, -9), (-5, 6)}

Answer 1

Domain is our x values. So for 1, it's just {4,-6,-3}, for 2 it's {1,3,0,-5}, et cetera. Do you think you can do 3?

Answer 2

Sorry, that should say that for 2 it's {1,5,0,-5}.

Answer 3

3. is {-12, -2, -1, 5, 7}

Answer 4

Yup! You got it.

Answer 5

4. is {-7, -5, -2, 1}

Answer 6

Yup.
