2. iheartfood

graph A (top) graph B (bottom)

3. iheartfood

graph C (top) graph D (bottom)

4. iheartfood

btw, the graphs are the answer choices :)

5. Hero

I'm about to run and hide.

6. iheartfood

why? haha =P lol

7. Hero

Because I've helped you with plenty of these exact kinds of problems. You should understand how to do them by now.

8. Hero

And you probably still haven't learned how to use your graphing calc.

9. iheartfood

ohhh haha :P yeah i just don't know how to tell if its the graph with that particular kind of function... we've done other kinds of functions b4 but not these kinds... and I'm still not too familiar with my graphing calc... but yeah we did other kinds of functions b4 :/

lol normally you can also use the general form of a cube \[y=x^3\] \[y^{-1}=x^{1/3}\]FORM|dw:1353890445166:dw| |dw:1353890513388:dw|

WE CAN LOOK 4 A GRAPH OF THIS FORM |dw:1353890624293:dw|

12. iheartfood

ohhh i see, so in this case, we automatically get graph B as our answer?

YES

14. iheartfood

oh cool! thx :)

15. Hero

Actually, there was a negative sign afront that function, so you also have to flip it over the x-axis as well @jonask

16. Hero

@iheartfood

|dw:1353892068426:dw|i had flipped it without showing sry

18. Hero

Bro, you're going to end up confusing her even more. Just post them on separate drawings.

I cant do that

i mean i cant do it like that i made mistake

21. iheartfood

wait what just happened?? so my answer isn't graph B?

@Hero how do you do it normally

23. Hero

All you had to do is post them on separate drawings. No, it is not B.

24. iheartfood

kk so how do we find the right answer then?

25. Hero

@Jonask, we're dealing with -x^1/3, not -x^3

i realized just now thanks ,its not really the same thing

27. iheartfood

kk so if its not B, then which graph is it? :O

|dw:1353892609349:dw| |dw:1353892711812:dw|so we need to put - in front ie reflect in x-axis(y become -y) |dw:1353892786065:dw|

@Hero

30. iheartfood

so its actually either Graph C or Graph D?

31. iheartfood

cuz of the shape? of the graph?

but it is shifted to the left so the 1 ont the left is correct

x+d means d units to the left

34. iheartfood

so is that graph C or D? :O

C

36. iheartfood

okay :)

37. iheartfood

thx :)
