Solve the problem.The following data represents the normal monthly precipitation for a certain city in California. 
Draw a scatter diagram of the data for one period. Find a sinusoidal function of the form 
that fits the data. Draw the sinusoidal function on the scatter diagram. Use a graphing utility to find the sinusoidal function of best fit. Draw the sinusoidal function of best fit on the scatter diagram.
What will be an ideal response?
y = 3.14 sin (0.46x + 1.52) + 3.16
