1. ChrisV Group Title

$2/\sqrt[3]{x}$

2. ChrisV Group Title

oops 2/x^3

4. ChrisV Group Title

when you have a negative exponent you just drop the value to the denominator

5. ChrisV Group Title

x^-3 is the same as 1/x^3

6. ChrisV Group Title

so 2(1/x^3)=2/x^3

7. ChrisV Group Title

i guess thats what you are looking for since you give no further directions

8. ChrisV Group Title

what is it you are trying to do?

horizontal translation equation

10. ChrisV Group Title

sec

11. ChrisV Group Title

did they give you a point?

no I just need to make up an equation and graphing

13. ChrisV Group Title

I am confused because normally for a horizontal translation a point is given

I have to create a horizontal function coming up with the points

15. ChrisV Group Title

so in other words i can plug 0 in for x and find my own point?

yes

17. ChrisV Group Title

well x cant be 0 so lets do 1 then

ok

19. ChrisV Group Title

f(1)=2/(1)^3=2

20. ChrisV Group Title

so if x = 1 y = 2

21. ChrisV Group Title

2=2/(1-a)^3 2=2/1-a^3 2(1-a^3)=2 1-a^3=1 -a^3=0 a=0 which this would not change the equation, not having a point given confuses me >.<

22. ChrisV Group Title

23. ChrisV Group Title

y=1/4 so 1/4= 2/(2-a)^3

24. ChrisV Group Title

14=2/(8-a^3)

25. ChrisV Group Title

1/4(8-a^3)=2

26. ChrisV Group Title

(1/4(8-a^3)=2)4

27. ChrisV Group Title

8-a^3=8

wait wait ok, I'm confused now too without an point given. Ok so example : f(X)= 4^3-x is horizontal equation. How would that be solved?

29. ChrisV Group Title

-a^3=0

30. ChrisV Group Title

so a agaon would = 0

meaning it would touch the line?

can't you plug in x value's ?

33. ChrisV Group Title

meaning the new equation which would be y=2(x-a)^3 would not be a change

34. ChrisV Group Title

y=2(x-0)^-3

35. ChrisV Group Title

if a is 0 there was no shift

ooh ok

37. ChrisV Group Title

this is why i dont like it when they do not give me a point to work with >.<
