    you're given a list of 4 choices I would plot each choice and see which one lines up with the given graph (focus on points like (0,0) and (pi, 0), etc)

    to make things easier to see, make sure the color of each graph is different

    if things get too cluttered, you can individually turn off graphs so they don't show up on the display

    what I'd do is look at each one individually one at a time turn off graphs 2-4 and focus on graph 1

    very good you can click on the x-intercepts and the point coordinates will show up you'll see (0,0), (pi,0), (2pi,0), etc
