first can you tell me what g(2) is?

g(x) = 3x g(2) = 3*2 ... replace EVERY x with 2 g(2) = 6

(f o g)(2) = f(g(2)) (f o g)(2) = f(6) (f o g)(2) = ???

jim_thompson5910Best ResponseYou've already chosen the best response.1
so how do you find f(6)?

jim_thompson5910Best ResponseYou've already chosen the best response.1
f(x)= 3/x f(6)= 3/6 f(6) = ???

jim_thompson5910Best ResponseYou've already chosen the best response.1
what do you get?

jim_thompson5910Best ResponseYou've already chosen the best response.1
so is (fog)(2)=2 true?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
but we just found that f(6) = 1/2 which pointed to the fact that (f o g)(2) = 1/2

Katieann16Best ResponseYou've already chosen the best response.0
but that isnt a choice on the answers?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
so that rules out choice A

f(x) = 3/x f(0) = 3/0 is that possible?
