    Transformation help

    I'm doing the review package for my transformations test tomorrow. I seem to be stumped on one type of question.

    If the point (6,-12) is on the graph of y=f(x), which point must be on the graph of y=f(-1/3x+6).

    a) -36,-12
    b) -24,-12
    c) 0,-12
    d) 16,-12

    I've tried taking the x, which is 6, dividing it by -1/3 and then moving it 6 to the left, but that doesn't work. Any advice would be amazing.

    Which is it: -1/(3x) + 6, or (-1/3)(x + 6), or -1/(3x + 6)?
