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)

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

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

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

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.

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

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

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

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)
