## mathcalculus 2 years ago Helppppppp :( For the following function, h , determine the functions, f and g so that : h(x)= f(g(x)) If h(x)=(8x+8/11x-11)^7 then f(x) g(x)

1. Mertsj

f(x)=x^7 g(x)=(8x+8)/(11x-11)

2. mathcalculus

so then do i plug in the equation in x^7?

3. Mertsj

I thought the problem asked you what the functions f and g are

4. mathcalculus

yup

5. mathcalculus

can you show me what the next steps are? i'm a bit confused..

6. Mertsj

The problem told you that the f(g(x))=

7. mathcalculus

steps

8. mathcalculus

i know what the problem said but can you show me?

9. Mertsj

$(\frac{8x+8}{11x-11})^7$

10. mathcalculus

okay.. i did that

11. Mertsj

Then it asked you what the f(x) is and what the g(x) is. So can you see that the f(x)=x^7 and you replace x with (8x+8)/(11x-11) that you will get the f(g(x))? There is really no work to show. It's just to demonstrate your understanding of function composition.

12. mathcalculus

there is work to show

13. mathcalculus

how can they give us a problem without any work???

14. Mertsj

Supposing they ask you what 4 x 3 is. Would there be work to show?

15. mathcalculus

after you found f(x)= x^7 when you plug in 8X+8etc etc.... what is the number or answer from there?

16. Mertsj

I'm thinking you don't know what the problem is asking.

17. mathcalculus

of course I can. I can show 4 columns and 3 rows of apples to equal to 12!

18. mathcalculus

i do. I submitted the "answer" of not showing the work.... hint hint wrong

19. mathcalculus

there is work. its math buddy

20. Mertsj

The problem says if h(x)= ... Then f(x)= and you should write x^7 g(x)= and you should write (8x+8)/(11x-11)

21. mathcalculus

yes i did

22. Mertsj

And?

23. Mertsj

24. mathcalculus

I see...

25. mathcalculus

thanks so much :)

26. Mertsj

yw. sorry

27. mathcalculus

lol no worries, again thank you.
