the trick

[graceful wraith]

What

[orchid carbon]

is to find

[graceful wraith]

Is it

[orchid carbon]

how to plug it

like

Yes I know that but

I don’t get the answer that I need

@orchid carbon

[orchid carbon]

well

lets say

$f(x)=x^2$

[uneven thorn]

yoavmal

[orchid carbon]

and $g(x)=\sqrt{x+1}$

[uneven thorn]

yoavmal

[orchid carbon]

$(g\circ f)(x)=g(f(x))=g(x^2)=\sqrt{x^2+1}$

Ok if I give you some answers will you say if I’m right or wrongs

?

[orchid carbon]

i'll give you ways to check

[graceful wraith]

What does that mean

[orchid carbon]

that you'll be able to tell yourself

if it's right or wrong

[graceful wraith]

Would it be $x^2/2x^2-2x+1$

[orchid carbon]

edit it so there's two dollar signs

one at the end as well

$\circ x^2/2x^2-2x+1$

[uneven thorn]

bojiden

Would it be $x^2/2x^2-2x+1$

[orchid carbon]

no idea

but

if it is

for every value you pick
