    1) give a simple set of transformations which when applied in sucession take y=x^2 to y=4-2x+x^2

    i dunno how to do this because i dont understand where the -2x comes from!

    2)write down two simple transformations that will transform
    y=cos x
    to
    y=sin(3x+1/2 pi)
    does the order of transformations matter?

    for this one i thought it would be a stretch in x direction factor 1/3 then translate 1/2 pi in neg x direction but the answer says the other way round could someone explain?

    thanks alot

    y=f(x-1) + 3.

    y=cos x

    Try using the fact that cosx = sin[0.5pi-x].
    I don't think order of transformations matters.
