Question

find formulae for fogoho ?
f(x)=x power 2 + 1 , g(x)=1/x , h(x)=x power 3

Answer 1

\[
(f\circ g\circ h)(x) = f(g(h(x))) = f(g(x^3))=f\left(\frac{1}{x^3}\right) = \left(\frac{1}{x^3}\right)^2+1
\]

Answer 2

it is a answer ?

Answer 3

I dunno.

Answer 4

Does it looks like the answer?

Answer 5

no think next step is
1/x power 5 + 1

Answer 6

what you say?

Answer 7

How do you get power 5?

Answer 8

\[
(x^3)^2 = (x^3)(x^3)
\]

Answer 9

because in multiplications powers are add so 3+2 = 5

Answer 10

Yeah, but you're multiply \(x^3\) and \(x^3\). So it is 3+3

Answer 11

no i think its x power 5

Answer 12

Okay do you agree with this: \[
x^a\times x^b = x^{a+b}
\]

Answer 13

yup

Answer 14

Do you agree with this: \[
(x^a)^2 = x^a \times x^a
\]

Answer 15

no x power 2a is the answer what you say?

Answer 16

I say they're the same damn thing.

Answer 17

If a = 3, then 2a = 6. 2a is not 5

Answer 18

oh ya right so sorry its my mistake

Answer 19

next step is 1/x power 6 +1 ?

Answer 20

yeah.

Answer 21

1+ x power 6 / xpower 6 ?

Answer 22

i think this is the answer ?

Answer 23

r u there ?

Answer 24

\[\left(\frac{1}{x^3}\right)^2+1=\frac{1}{x^6}+1=\frac{x^6+1}{x^6}\]

Answer 25

1+x power 6 / x power 6 is right

Answer 26

if you mean (1 + x^6)/x^6 then yes :)

Answer 27

you mean i'm correct ?

Answer 28

if 1 + x power 6 is on top then yes :)

Answer 29

thanks
