I think what they mean by vertical displacement is how much it shifts on the y-axis away from the (0, 0) compared to a regular y=cos2x curve. If you have a TI 83 graphing calculator plug it in to see the graph. Also plug in y=cos2x and you'll notice that it in fact shifts by 2 on the y-axis. Or just plug x = 0. Adding to the global equation (ie. y= 560 + sinx, y= -10 + cos5x) only shifts the graph up and down the y axis. You'll change the curve only if you change the trigonometric function (ei. 5cos5x different from 4cos5x, different from 5cos2x etc...)
You're right.

you are correct!!
Thanks for putting your thoughts...and not just pasting your homework all over the place like others do.
But here is the question -- which "2" is the cause? The 2 in front, adding, or the 2 with the x?
Hopefully you guessed the one in front.
The 2 with the x causes horizontal shrinking or stretching.
