I have 12 different data tables and I am confused on my graph and using desmos. If I have a plot of a function f(t) then it must satisfy the definition of a function? I am confused on this am I supposed to have different starting days for each month? I did my data on the 4th day to the 28th day of each of the 12 months in a year. So 4-8-12 and so on so that I didn't do every single day in a month.
