Plot the points on the grid provided. Let January 1 correspond to x=0, February 1 correspond to x=1, etc, and let y=minutes of daylight. Connect the points with a smooth curve. It should look like a sine wave! b. Use your graph to find the amplitude, period, horizontal shift, and vertical shift of the function. (Note: It's reasonable to assume the minutes of daylight in January 2016 is the same as in January 2015. The length of a cycle is 12 months, so that's the period.) Then write a sine or cosine function to represent the data.
