    Post Transformations of f(x) = 6x - 2

    Hi, again!
    I am at a complete loss for this. I'm supposed to write an equation for each transformation of f(x) = 6x -2.

    Problem is, I don't know how.

    14) a vertical compression by a factor of 1/3 and a reflection in the y-axis.

    This is one of them and if I know how to do one I can figure out the rest of them. It'd be awesome if you would help me with this~ Please and thank you~

    Consider the homothety h:\mathbb{R}\to \mathbb{R},\;h(x)=6x and the translation t:\mathbb{R}\to \mathbb{R},\;t(x)=x-2 then, f=t\circ h .
