3 State the Domain and Range of the relation: {(8,5), (-6,-9), (2,5), (0,-8)}

D:{8,-6,2,0}: R:{5,-9.5,-8}
D:{5.-6.2.-8}; R:{0,-8.-2.-6}
D:(-6,0,2.8) : R:(-9,-8,5)

D:{8,-6,2,0}: R:{5,-9,5,-8}

Explanation:
The domain is x and the range is y, so I'll go through each coordinate;
(8,5) domain=8; range=5
(-6,-9) domain=-6; range=-9
(2,5) domain=2; range=5
(0,-8) domain=0; range=-8
So the answer is D:{8,-6,2,0}: R:{5,-9,5,-8}

Simplest Form: log2 (x/9)
