    say the graph is f(x)

    f(x+a) translation vector (-a,0)
    f(x) + a translation vector (0,a)

    kf(x) stretch factor K parallel to y-axis
    f(kx) stretch factor 1/k parallel to x-axis

    Basically if K hits inside the bracket it affects the x and if its outside the bracket it hits the y

    This what you were after?

    say f(x) is the original line,
    f(x+a) shifts the line a units in the negative x direction (to the left)
    f(x-a) shifts the line a units in the positive x direction (to the right)
    f(x)+a shifts the line a units in the positive y direction (up)
    f(x)-a shifts the line a units in the positive y direction (down)
    af(x) stretches the line by a factor of a vertically. (squash if a is less than one)
    f(ax) squashes the line by a factor of a horizontally (stretch if a is less than one)
    -f(x) reflection in x axis
    f(-x) reflection in y axis.

    i think thats all of them.
