I think it's A

2. hartnn

nopes

3. hartnn

domain is the values that x can take

4. hartnn

so from your figure, x can take the values from ?? to ??

5. Zekarias

I think hartnn gives u good explanation about what domain is. It is better if u try first. What can u say?

6. SephI

I don't understand...?

7. hartnn

ok, what all values can x take ? can x be = 10 ??

8. NewbieCarrot

domain=range of x codomain=range of y=the range of values of f(x)

9. Zekarias

Ok lets take domain=range of x, can u find this from the graph?

10. Zekarias

Can u do that?

11. SephI

X can take 3-7 values.

12. hartnn

yes! that would be your domain

13. SephI

Okay! I was think 3-12 because the graph goes from three, and then up 12.

14. hartnn

the values that the graph(or y) can take is called the 'range' of graph or function. sence, 3 to 12 is range of y.

15. SephI

What is it called when x and y values are written in the form (x, y) A pair?

16. hartnn

co-ordinates (2,3) 2 is x co-ordinate 3 is y co-ordinat

17. SephI

A relation is the output (y) values of the relation the input (x) values of the relation a set of points that pair input values with output values <--- This, correct x and y values written in the form (x, y)

18. hartnn

yes, a RELATION is simply the set of ordered pairs (x,y) so that is correct.

19. SephI

I have a few more.

20. hartnn

u can ask here or make a new post, suit yourself.

21. SephI

I'll make a new one
