Question

Help Meeee ):

Answer 1

if f(x)= 3/x & g(x)=3x which is true?
A) (fog)(2)=2
B) (gof)(0)=0
C) (fog)(9)=1
D) (gof)(-9)=-1

Answer 2

@zordoloom

Answer 3

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

Answer 4

no

Answer 5

g(x) = 3x

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

g(2) = 6

Answer 6

(f o g)(2) = f(g(2))

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

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

Answer 7

so how do you find f(6)?

Answer 8

f=3?

Answer 9

f(x)= 3/x

f(6)= 3/6

f(6) = ???

Answer 10

?

Answer 11

reduce 3/6

Answer 12

what do you get?

Answer 13

1/2

Answer 14

so is (fog)(2)=2 true?

Answer 15

yes

Answer 16

but we just found that f(6) = 1/2

which pointed to the fact that (f o g)(2) = 1/2

Answer 17

but that isnt a choice on the answers?

Answer 18

so that rules out choice A

Answer 19

so its B?

Answer 20

what is f(0)

Answer 21

f(x) = 3/x

f(0) = 3/0

is that possible?
