Unemployment The following table shows the number of unemployed persons in the U.S. in 1994, 2000, and 2008.

Take t to be the year since 1994 and y to be the number (in millions) of unemployed persons.

a. Model the 1994 and 2000 data with a linear equation.

b. Model the 2000 and 2008 data with a linear equation.

c. Use the results of parts (a) and (b) to obtain a piecewise linear model of the number (in millions) of unemployed persons for 1994–2008.

d. Use your model to estimate the number of unemployed persons in 2002.
