# Thread: find the composition of f & g.

1. ## find the composition of f & g.

For f(x)=3x^4-2x^2
&
g(x)=2/(x)^1/2 ,x=0

Find the composition of f and g.
First off, $x\neq0$ must be true in defining our $g(x)$

Now $\left(f\circ g\right)(x)=f\left(g\left(x\right)\right)=3(g(x))^ 4-2(g(x))^2=\dots$

Can you continue?

3. ## thanks

yes now i can continue it
thanks alot
i m love in it to use math help forum

4. ## Can you complete it
