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

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

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

    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?

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

    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)
