Problem 4 Got It?
  1. Create a table at desmos.com and use it to find a linear regression model of the cheese consumption data. Let x = years since 1900. Recall Desmos' linear regression notation: y1~ax1+b.
  2. Zoom and pan your graph to establish an appropriate viewing window that contains all data points and the regression line.
  3. Take a screenshot of your graph and upload or paste it to the Formative canvas.

Take Note: Define extrapolation. You may use the canvas to help illustrate your written definition.

Take Note: Consider modeling the data in the table.
Classify each year in the left column below based on whether estimating cheese consumption that year is an example of interpolation or extrapolation.
1995
2000
2019
1950
2050
1890
2005
Interpolation
Extrapolation
Problem 4 Got It? Use the model you created above to estimate cheese consumption for 1980, 2000, and 2012 algebraically and/or graphically. Remember that you were instructed to let x represent years since 1900.
Also, identify the prediction years in which you can have the most and least confidence.
Hint: Consider interpolation vs extrapolation.
26.31 lb
23.07 lb
21.53 lb
17.7 lb
1980
2000
2012
Estimated consumption in 1980
Estimated consumption in 2000
Estimated consumption in 2012
Two prediction years with greatest confidence
Prediction year with least confidence
Solve It! Based on the pattern in the table, find the total area when x is 5.
43 m²
58 m²
60 m²
53 m²
Solve It! What type of polynomial function does the data fit? Explain.
The data fit a linear function because the first differences are constant.
The data fit a quadratic function because the second differences are constant and the first are not.
The data fit a cubic function because the third differences are constant and the second are not.
The data fit a quartic function because the fourth differences are constant and the third are not.
