What are the domain and the range of the relation?

{(−3, 1), (−6, 7), (0, 9), (2, −1), (8, 8), (11, 5)}

Choose exactly two answers that are correct.

A.
domain: {−6, −3, 0, 2, 8, 11}

B.
domain: {–1, 1, 5, 7, 8, 9}

C.
range: {–1, 1, 5, 7, 8, 9}

D.
range: {−6, −3, 0, 2, 8, 11}

Respuesta :

domain is the set of numbers you input into the function

range is the set of numbers you get from inputing the input (output)

so (x,y) form
x=input
y=output
so just get all the x's or first numbers and that is domain
all y's are ranges

(-3,1), (-6,7), (0,9), (2,-1) (8,8), (11,5)

domain=-3,-6,0,2,8,11
range=1,7,9,-1,8,5
order from least to greatest

domain=-6,-3,0,2,8,11
range=-1,1,5,7,8,9
