Question

What are the domain and range of the relation (–4, 2), (0, 1), (0, 5), (8, 10)?

Answer 1

the domain is all the x values and the range is all the y values. Do not list duplicates.

domain (x values) = (-4,0,8)
range (y values) = (2,1,5,10)

Answer 2

use second bracket because domain and range are sets.

Answer 3

for this reason, we are not repeat the values in domain or codomain

Answer 4

domain={-4,0,8}, range={2,1,5,10}
