this is meant for you to visualize the horizontal asymptote is the horizontal line that the graph approaches as it goes to the right $$\infty$$ and to the left $$-\infty$$

3. anonymous

they have marked it for you with a dotted line the vertical asymptote is the vertical dotted line. it is hard for me to read, but i think that is the line $$x=-1$$

4. anonymous

there are no "oblique asymptotes" otherwise you would see a non vertical line dotted

5. anonymous

the domain is all real numbers except where you see that you cannot plug in a value of $$x$$ which not coincidentally is the vertical asymptote in other words it is all real numbers except for $$x=-1$$

6. anonymous

For domain, how far can x go before being intervened by an asymptote. Same for y. Intercepts, when an x value touches the x-axis or the y value touches the y axis. And you should know asymptotes and what are they. (DOTTED LINES). Give equations and be done with it. Considering this is a test based on what you learned over lessons, I cannot help you further.

7. anonymous

and similarly you can see from the graph that the function approaches, but never actually achieves the value of $$y=3$$ which is the horizontal asymptote

8. anonymous

ohh i see

9. anonymous

and finally the "intercepts" are where the graph crosses the $$x$$ axis, and where the function crosses the $$y$$ axis. it looks like they are at the same place, since the graph crosses both axes at $$(0,0)$$

10. anonymous

so domain is (-infinity to infinity?

11. anonymous

if you have any question let me know. no

12. anonymous

all real numbers except -1

13. anonymous

domain is all real numbers except $$x=-1$$

14. anonymous

right

15. anonymous

and range all real numbers except 3?

16. anonymous

yes

17. anonymous

x-intercept -1?

18. anonymous

or 0?

19. anonymous

i think x-intercept is -1 and y intercept is 3

20. anonymous

no the intercept is where it crosses the $$x$$ axis, for the $$x$$ intercept it is not the same as the asymptotes

21. anonymous

so 0

22. anonymous

it crosses the $$x$$ axis at $$(0,0)$$

23. anonymous

your answer should be an ordered pair $$(0,0)$$

24. anonymous

well it asks only for the x intercepts

25. anonymous

no actually it says "the intercepts" but it is the same answer for both

26. anonymous

27. anonymous

oh i see well zero for both

28. anonymous

ok and vertical is -1 and horizontal?

29. anonymous

$$y=3$$ is the equation of the dotted horizontal line

30. anonymous

ooh wow

31. anonymous

lol

32. anonymous

i have another problem

33. anonymous

post, you will get lots of answers some may even be right
