    A. all negative values of f(x) become positive so the part of the graph below the x -axis is reflected in it.

    oh I'm taking the graph at the bottom to be the parent function

    well yes - if f(x) is the curved function in your first post.

    d is a stretch of the graph para;;;e; to the y-axis factor 2 |dw:1440283028819:dw|

    the whole graph will be stretched ' up and down'

    * parallel to y axis.

    yes thats right the point at y = 6 moves up to y = 12 - factor of 2

    and should I make the period skinnier, or does it stay the same?

    oh the minimum at y=-2 so only go down to -4

    Oh, my bad I see that. and does the period (x) stay the same, or should i compress it?

    well the whole thing will look skinnier i dont think they want you do draw it absolutely accurately - just a good sketch

    But do the points stay the same for x?

    for e it will stretch the graph horizontally with factor 2

    if we take y = x^2 then 2 x^2 will look like as follows |dw:1440284048772:dw|

    Oh, so there are two points for the graph. (-4,2) and (8,2). Do I keep them, or should I change them. And how if so?

    oh sorry the x points do stay the same (-4,2) will become (-4,4) and ( 8,2) will move to (8,4)

    right e is a stretch parallel to x axis so x points will change y points will stay the same
