Question

Find f(x) and g(x) so the function can be expressed as y = f(g(x)).

y =8/x^ + 4

Answer 1

not real sure about the notation

Answer 2

sqrt(..) helps to define the radical

Answer 3

sorry, there shouldn't be a sqrt...

Answer 4

a little better, what does /x^ +4

mean?

Answer 5

8 divided by x squared plus 4

Answer 6

\[1)~\frac{8}{x^2+4}\]\[2)~\frac{8}{x^2}+4\]

Answer 7

2 opition :)

Answer 8

now its clear :)

Answer 9

\[f(x)=x+4~;~g(x)=\frac{8}{x^2}\]
\[f(x)=\frac{8}{x}+4~;~g(x)={x^2}\]
\[f(x)=\frac{8}{x^2}+4~;~g(x)=x\]

is there anymore info to go on? otherwise you can create quite a few options

Answer 10

\[f(x)=2(x+2)~;~g(x)=\frac{4}{x^2}\]

Answer 11

one might imagine infinitely many

Answer 12

Yiu should be able to have a few different choices, but none of those distribute an x to the 4?

Answer 13

why would you need to distribute an x to the 4 ?

Answer 14

You don't I'm just verifiyng.

Answer 15

I see now! Sorry! Thank you so much :)

Answer 16

any setup that combines g into the x part of f should suffice
