   Student Task Statement

   Here is a graph of given by .

   1. Are and in the domain of ? Explain how you know.
   2. What are the -intercepts of the graph of ? Explain how you know.

   

   A graph. Horizontal axis, theta, scale 0 to 2 pi, by pi over 2. Vertical axis, y, from negative 3 to 3, by 1s. A curve begins at 0 comma 0 and curves upward towards an invisible vertical line at pi over 2 but never touches it. Another curve crosses the x axis at pi. It continues in both directions, up and down, approaching invisible vertical lines at pi over 2 and 3 pi over 2, but never touches them. Another curve crosses the x axis at 2 pi. It continues down only approaching an invisible vertical line at 3 pi over 2 but never touches it.
