Question

f(x)=x-1/x+2, g(x)=1/x

Answer 1

what is the question

Answer 2

find function of f & g

Answer 3

what kind of function?
could be (fog) of f(x)/g(x) or f(x) + g(x)
needs to be more specific

Answer 4

(fog) (x)= f(g(x))

Answer 5

ok, then all you need to do is substitute the x from the function f(x) with 1/x

Answer 6

you have f(x) = x-1/x-2
so it would be (1/x)-1/(1/x)-2

Answer 7

would the answer be -x+1/x+2?

Answer 8

do you have choices

Answer 9

im not sure if i did it right

Answer 10

the answer I get is the one that I showed you, don't think you can do anything else

Answer 11

so it will be f(x)= (1/x)-1/(1/x)-2

Answer 12

or i dont need to put f(x)?

Answer 13

actually now would be as follows:

f(g(x)) = then the answer

Answer 14

one last question about f(x)=x-1/x+2, g(x)=1/x, how come your answer change the sign to (1/x)-1/(1/x)-2, the +2, became -2

Answer 15

sorry you are right it is +2, it doesn't change, the only thing I did was substitute the x for 1/x

Answer 16

thank you, got it! ur a big help

Answer 17
