Problem:f(x) = 2 cos 1/2 (x). On a sheet of paper, graph the function in degrees. Determine the function's y-intercept, amplitude, interval, period, and the four x-values that mark the location of its quartiles.

Responses:    y-intercept = (, )
   amplitude =
   interval = [, ]
   period =

   quartile 1 =
   quartile 2 =
