Question

f(x)= 2x/x+3 and g(x)=5/x
find:
(f o g)(x) ?

Answer 1

@marsss

Answer 2

hey @Mertsj :D

Answer 3

f composite g means to replace each x in the function f with the function g

Answer 4

2(5/x) / (5/x)+3 right ?

Answer 5

f o g means f(g(x))

if g(x) = 5/x and f(x) = 2x/(x+3)

Then f o g = 2(5/x)/(5/x + 3)

Answer 6

ok cool :) but I'm stuck from there...
