Question

Which of the following sets represents the domain of the function shown?
{(2, 7}, (15, 13), (21, –4), (24, 18)}

Answer 1

those are the answer choices.
A) {-4,2,7,13,15,18,21,24}
B) {7,2),(13, 15),(-4,21),(18,24)
C) {2,15,21,24}
D) {-4,7,13,18}

Answer 2

Domain includes all unique x-values right?

Answer 3

domain = set ,with first element

Answer 4

yea

Answer 5

So which one is it? Look at the x values...

Answer 6

i really dont know i not good at math! :'(

Answer 7

When you graph, you have (x,y) values right?

Answer 8

That's what's given, so the x values are your domain and y is your range.

Answer 9

yea, so?

Answer 10

So what's the answer then compared to your choices?

Answer 11

D? what did you think

Answer 12

Look at your values, it's put in (x,y)
(2,7) -> 2 is your x, 7 is your y, the 2 is part of your domain, the 7 isn't, it's part of the range.

Answer 13

Oh wait! is B? :/

Answer 14

No we want JUST the domain

Answer 15

Don't guess, think about what I just said

Answer 16

A?

Answer 17

When you graph, you have points as (x,y) right?

Answer 18

all the x values in your function represent the domain, and the y values represent range.
So if you had something like {(1,2), (4,3), (5,3)} your domain would be {1,4,5}

Answer 19
