3. iheartfood

GRAPH!

use $x^{\frac{ 1 }{ n }}=\sqrt[n]{x}$

5. iheartfood

ANSWER CHOices: A. n is a positive even integer. B. n is a positive odd integer. C. n is a negative even integer. D. n is a negative odd integer. ***idk :(

6. iheartfood

idk how to use that :( can u pls show me?

7. iheartfood

I'm really confused :( math is not really my thing :P lol but how do i use it?? I'm still confused :(

we are given in power form and we have to change to root form using the rule$x^{1/n}=\sqrt[n]{x}$ so$y=a \sqrt[n]{x+k}+C$ is our graph we will now choose an obvios point (9,-4) and put in the equation

9. iheartfood

okay so what do we get when we do that?

n=2 and even|dw:1352840447816:dw| the graph is in this form

@hartnn

this graph is an inverse of a parabola so n is positive and even

13. iheartfood

so my answer is A? A. n is a positive even integer. ??

$y=a \sqrt[2]{x-5}+2$

yes

16. iheartfood

okay, so answer A it is then! :) thank you :)

yes

18. iheartfood

kk thx :)
