Question

Find the domain of the relation below.
(4,2), (-2,4), (0,1), (1,5)
A) {4,-2,1,5}
B) {2,4,1,5}
C) {4,2,-2,4,0,1,1,5}
D) {4,-2,0,1}

Answer 1

The domain of a function is always the 'input' while the range is 'output'

Ex. Find the domain of (2,8)
The domain or 'input' is 2, while the range or 'output' is 8

So can you figure it out?

Answer 2

SO it'd be C?

Answer 3

I just suck at math .-.

Answer 4

No because C has both the domain and the range while you only want the domain.

Answer 5

Oh I get it so it'd be D

Answer 6

Yes! You got it (:

Answer 7

Answer 8
