verify the functions are inverses of each other by showing that f(g(x)) =x show work.
f(x)=6/1-x g(x)= 1- 6/x

  • precalculus - ,

    I will assume f(x) = 6/(1-x)
    f(g(x))
    = f(1 - 6/x)
    = 6/(1 - (1 - 6/x)
    = 6/(1-1+6/x)
    = 6/(6/x)
    = 6(x/6)
    = x

    these are hard to do - thank you
