    Logarithms Help

    Can someone please tell me if the following questions are right or wrong. I did all the work, I'm just looking to see if it's correct or not... if it's not correct how do i fix it.... Please note that terms are very important (stretch/compress... factor etc)... I've had some trouble in the past with those.


    Question

    y = 2log[-2(x - 1)]

    Answer

    Vertical stretch of 2, Reflection in y axis, Horizontal compression of 1/2, Right 1



    Question 2

    y = -3log[(x + 4)] - 5


    Answer

    Reflection in x axis, Vertical stretch of 3, Left 4, Down 5


    Question 3

    y = (1/2)log[ (1/3)(x)]

    Answer:


    Vertical compression of 2, horizontal stretch of 3


    please help me out for this... I've done all the work but I just need to know if it's right or wrong... If ti's wrong what did I do/say wrong... If i need to say "factor of 2" for example, where would I say it, etc.. or if it's fine the way I did it then that's even better..

    Thanks a lot guys
