what is f(composed)g(x) if x does not equal -4/6

please help me

  • College Algebra URGENT - ,

    (fog)(x) is also f(g(x)) which means you substitute g(x) to the function of f(x),, (the x variables in f(x) will be g(x)), thus:
    (fog)(x) = 1/([g(x)]+4)
    (fog)(x) = 1/[(1/(6x+4) + 4]

    then simplify it.
