First Differences are Constant First Differences are constant for awhile and switch to the negative of the constant value. Second Differences are Constant but First Differences are not. Third Differences are Constant but Second Differences are not. \, Ratios or Ratios of First Differences are Constant The patterns given above allow you to determine with absolute surety that a data set represents a specific type of function. However, many functions have general patterns in their first differences. If none of the above patterns are true of the function you are filling this sheet out about, describe the general pattern you see in the first differences in the space below. (For instance, "The first differences are small, then large, then small again”) Print an example data set from the function family spreadsheet used earlier, and put it immediately after this sheet. If this type of function has any of the patterns listed above, make sure this is shown on your printout. Real World Applications List the real world applications of this type of function talked about on the Guide Sheet or in the lab. For each application listed, indicate what real world quantity is the input and what real world quantity you get as an output. Be very specific and give as many details of the application and its inputs and outputs as you can.
