Those are the graphs and the problem.

Isn't the attachment 2 and 4 same?

6. kirk.freedman

Sorry, I screwed that up, lemme re-try

7. saifoo.khan

Okay. So now which one do you think it should be?

8. kirk.freedman

I really have no idea :P

9. saifoo.khan

Do you know how the radical graphs looks like?

10. kirk.freedman

Hmm, well I guess, kinda, what do you mean?

11. saifoo.khan
12. kirk.freedman

Oh yeah, I got that.

13. saifoo.khan

Now try to answer the problem/

14. kirk.freedman

Lol, sorry, but how? Where do I start?

15. saifoo.khan

See the "shapes" of the graphs. Match them one by one.

16. kirk.freedman

I'm so confused :/

17. saifoo.khan

Do you agree that the problem given to your in a cube-radical?

18. kirk.freedman

Yes.

19. saifoo.khan

Okay. No see the shape of cube-radical: http://www.wmich.edu/cpmp/parentresource/images/c2u4graph6.jpg Now match the options one by one.

20. kirk.freedman

Well it looks like b and c are most similar?

21. saifoo.khan

Right! Now your problem says 2 ^3√(x+2)+4 Since it's +4, it should be above the value of zero. As in case of opt 2. If it were let's say -1, then it would have been below 0 as in opt 3.

22. kirk.freedman

So it's b?

23. saifoo.khan

Yep!

24. kirk.freedman

Thanks!
