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

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

When you graph, you have (x,y) values right?
Astrophysics
  • Astrophysics
That's what's given, so the x values are your domain and y is your range.
anonymous
  • anonymous
yea, so?
Astrophysics
  • Astrophysics
So what's the answer then compared to your choices?
anonymous
  • anonymous
D? what did you think
Astrophysics
  • Astrophysics
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.

Oh wait! is B? :/

No we want JUST the domain
Astrophysics

Don't guess, think about what I just said

A?
Astrophysics
  • Astrophysics
When you graph, you have points as (x,y) right?
Astrophysics
  • Astrophysics
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}
