Maximal domain of g(x)...
g(x) = (3)  (4/(x+2))
Is it x + 2 = 0..
x =  2...
Is that how we get the maximal domain??

Best ResponseYou've already chosen the best response.0The maximal domain is the set of all x that allows your function to exist.

Best ResponseYou've already chosen the best response.0So here, your function is not defined at the point x=2 since there, the denominator is 0.

Best ResponseYou've already chosen the best response.0so it can't equal to zero because it's over something

Best ResponseYou've already chosen the best response.0So your domain is the set of all x real except for x=0.

Best ResponseYou've already chosen the best response.0i think real, as long as X not equal to 0

Best ResponseYou've already chosen the best response.0so is the answer...? R / 2 ?

Best ResponseYou've already chosen the best response.0\[\mathbb{R}  \left\{ 2 \right\}\]

Best ResponseYou've already chosen the best response.0Also what is it's range? + it wants the inverse...

anonymous

Best ResponseYou've already chosen the best response.0is the range infinity to 3 ?

anonymous

Best ResponseYou've already chosen the best response.0u want this (infinity,2),( 2, infinity)? but i never see a form like that, u just write R{2}

anonymous

Best ResponseYou've already chosen the best response.0Okay, do you know how to get the inverse?

anonymous

Best ResponseYou've already chosen the best response.0You can use the definition for the inverse. g is the inverse of f if \[f(g(x))=x=g(f(x))\]

anonymous

Best ResponseYou've already chosen the best response.0The inverse of your function can be found then as,\[f(g(x))=3\frac{4}{g(x)+2}=x\]and solve for g(x).

anonymous

Best ResponseYou've already chosen the best response.0do we put the w hole g(x) under that 4 ?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0oh sorry.. do we re arrange the g(x) to the other side or something?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0yeah, you solve for g(x)

anonymous

Best ResponseYou've already chosen the best response.0oh lol, 1 = x (g(x) + 2)

anonymous

Best ResponseYou've already chosen the best response.0\[3\frac{4}{g(x)+2}=x \rightarrow g(x)=\frac{4}{3x}2\]

Best ResponseYou've already chosen the best response.0check, i'm being distracted by different people

anonymous

Best ResponseYou've already chosen the best response.0g(x) = 3 4/x+2.... and inverse is 3  4/g(x) +2... can you just leave it like that?

anonymous

Best ResponseYou've already chosen the best response.0y = 3 (4/x+2) x = 3(4/y+2) and then simplify

anonymous

Best ResponseYou've already chosen the best response.0Take your original function. Put g(x) in place of x and replace f(x) with x Solve (rearrange) so you have g(x) = blah blah

anonymous

Best ResponseYou've already chosen the best response.0how to simplify after... 1 = x(g(x) + 2) ?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0x(g(x)+2) = xg(x) + 2x

anonymous

Best ResponseYou've already chosen the best response.0subtract 2x from both sides

anonymous

Best ResponseYou've already chosen the best response.0but i think you've made a mistake

anonymous

Best ResponseYou've already chosen the best response.0it wants the inverse g^1... of g(x) = (3)  (4/(x+2))

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0y = 3 (4/x+2) x = 3(4/y+2) x(y+2) = 34 x(y+2)=1 y+2 = 1/x y = (1/x) 2 can this make sense?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Yeah, same thing, different notation.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0yeah it makes sense except the G^1.... the inverse... it looks different.

anonymous

Best ResponseYou've already chosen the best response.0I stuffed the g(x) calc. because I'm writing it out on this damn thing, but the procedure is correct

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0=) Okay so should I just replace the y's with g(x).. as the answer?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0You should end up with\[g^{1}(x)=2\frac{x1}{3x}\]

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0no no ... don't just replace the y's with g(x)... Do what I said... Take your original function. Put g^1(x) in place of x and replace f(x) with x Solve (rearrange) so you have g(x) = blah blah

anonymous

Best ResponseYou've already chosen the best response.0it looks difficult to do but okay :)

Best ResponseYou've already chosen the best response.0You know what, there's a lot of confusion here. I'm going to write it out and scan.

Best ResponseYou've already chosen the best response.0Ive reformatted my pc so ill down pdf reader now, thanks for the link.

Best ResponseYou've already chosen the best response.0Lokisan, did you use the retro version of this site?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Yes, there was another version to this site

anonymous

Best ResponseYou've already chosen the best response.0That means you joined it after the changes have taken place

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Well, I think the retro was better, as you could type there realtime

anonymous

Best ResponseYou've already chosen the best response.0I mean, it was more like a black board, and we didn't have to wait for the whole typing to be over

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Further more we could erase typed things and we could also type inbetween others' typings

anonymous

Best ResponseYou've already chosen the best response.0yeah, this is a pain, and i can't use this site on my phone  not practical

anonymous
