Write a MATLAB function named Keeling_Curve

The function will have two inputs and two return values

The first input will be a list of numbers corresponding to monthly atmospheric carbon dioxide concentrations from Hawaiis Mauna Loa Observatory

The second input will be a list of the corresponding dates

The function must generate a plot of the carbon dioxide concentration vs the corresponding dates

For this exam, you will not be graded on the plot, plot title or axis labels.

The first return value must be the maximum atmospheric carbon dioxide concentration

The second return value must be the number of datapoints
