Ihave to finish this in two hours you so much!

see graph attached

Explanation: Remember that sin has a period of 2pi, so one single sine "wave" (+ and -) will fit in the right hand side (and another on the laft hand side). Next, recall that sin(x) has a maximum amplitude of 1 and minimum of -1, so sin(x) -2 will be varying between -1 and -3. Finally, sin(x) crosses the x axis at pi, so sin(x)-2 crosses the horizontal line at -2 at the point pi. That gives you sufficient information to draw the graph, as asked. Compare the image I attached to double check your work.
