Question

f(x)=(x-7)/(x+2), g(x)= (-2x-7)/(x-1)
Can anyone show me how to find the F(g)(x)) and g(f)(x))? and show how they are inverses?

Answer 1

yes

Answer 2

F(g(x)) is found by treating the value of g(x) as x and inserting it in f(x)
f(x)=(x-7)/(x+2)
F(g(x)) = (g(x) - 7)/ ( g(x) + 2)

Can you put the calue of g(x) & evaluate further from here

Answer 3

ohhh okay wait I think I figured it out.. nevermind! Thanks though!:)

Answer 4

yw:))) do ask if you need any help
