Question

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

y = 8/x^2 + 4

Answer 1

g(x) = x^2 and
f(x) = ?

Answer 2

f(x) = 8 or 12? still confused

Answer 3

Substitute u=x^2 in your equation above. y=f(g(x))=f(u)=...

Answer 4

So i would multiply 8 by x^2? BTW thank you for the help!

Answer 5

No, it looks like in your equation above you have 8/x^2+4=8/u+4

Answer 6

I just gave you the answer. Whoops!

Answer 7

That would be the final answer? hm i was thinking totally something different...

Answer 8

ohhh i gotcha thank you so much
