    Alright g is on the inside, so you are going to put the function g, into the x of the function f

    first analyze it the question is find f(g(x)) you already know that f(x) = -4x + 7 and g(x) = 10x - 6...but in the question there is no f(x) but there is just an f so what would you do to find f

    you would take away the x from the equation so it would be f=-4+7

    Why does he need two opinions? alright thebroski I want you to work it out yourself, start by putting g(x) into the x in f(x)

  32. snowskimwake

    f(x) = -4x + 7 and g(x) = 10x - 6, so g(x) goes into f(x = -4(g(x) goes here) + 7

    i'm not going to ban u for asking for help, in fact i'll help you if i can. it just doesnt seem like u really want the help though. sounds like u just want the answer cos it's quite a long thread and u still don't get it... reposting the question with the possible answers doesn't get u so far on this site. be patient, and try at least, to understand :)
