f(x) = 4x  7, g(x) = 6x + 8 ... find (fg)(x) (my answer is 24x^210x56 ... does this look right?)

Best ResponseYou've already chosen the best response.0or were you looking for f(x)*g(x)?

Best ResponseYou've already chosen the best response.0That usually means f(g(x)), but notation does sometimes vary..

Best ResponseYou've already chosen the best response.0f(g(x)) is written like that, f(g(x))

Best ResponseYou've already chosen the best response.0Actually, you will find that I am right, I am a statistics and economics major at UC Berkeley. Check this article to verify: http://www.ehow.com/how_5203413_fgx.html :)

Best ResponseYou've already chosen the best response.0I know, why don't you troll a bit and throw insults at people randomly because they can't see you or reply to your face. People show no respect on the internet.. we are both trying to help someone, can't you see that and put petty insults aside? I think the notation is unclear: here is another topic where people are discussing the same issue: http://www.physicsforums.com/showthread.php?t=237718

Best ResponseYou've already chosen the best response.0the answers all are polynomials...it is multiple choice. they are all squared so i think it would be fx*gx

Best ResponseYou've already chosen the best response.0lols man , confirmed my theory, math students are completely useless :P . Seriously some of guys lack common sense, you can do all your pure maths which has no applications to society but you cant even apply common sense lol

Best ResponseYou've already chosen the best response.0whoa, you got a math degree, big deal , I am second year engineering student ( probably done like 1/10 of the amount of maths you have ) and I have more common snese than you
