  1. The amplitude is 1/4.
    Since the variable is x and not time, they should ask for the wavelength L, not the period.

    2 pi/L = 3/4

    L = (8/3)*pi

    There is a horizontal shift of -pi/8 radians

    We don't do plots. I suggest you make your own table of values and draw the graph. It will help you understand how the answers come about.
