Answer 3

first arrange values as follows:

(4,1), (5,3), (5,1),(5,4),(6,5),(6,4),(7,8)

Answer 4

ok

Answer 5

ok, now lets see if the answer are true, range are the values of y
so what are the values of y when you have points (x,y)

Answer 6

second choice said 3 is an x- coordinate
do you see any 3 in the place of the x - coordinate ???

Answer 7

third choice 8 comma 7, which is (8,7) is an ordered pair
do you see any (8,7) on the ordered pairs ??

Answer 8

there are 7 elements on the domain,
domain are the values of x, and if you have a repeated valued only counts as one

Answer 9

ok

Answer 10

there are no 3's in the x coordinate

Answer 11

correct, so that is not a good choice
what else?

Answer 12

i do not see 8,7 in any ordered pairs

Answer 13

that is correct as well, so that is not good either

Answer 14

so that means that there are 7 elements in the domain

Answer 15

let see, domain are values of x so
domain {4,5,6,7} do you see any other ?
there are 4 elements

Answer 16

no

Answer 17

ok, so let see the range are the values of y
range: {1,3,4,5,8}

Answer 18

ok

Answer 19
