  2. huh??
    for your first ... /(x+2) , x is not equal to -2

    so in " .. x is not equal to k" , I guess k must be -2

  3. Ok, your turn for #2, I have given you several examples.
    It is really easy.

    See if you can get p = 2

  6. find g^-1 (x) the way I showed you

    from that get f^-1(p) , then
    find f(4)

    set those two equal to each other and solve
