The numbers D of doctorate degrees (in thousands) awarded to female students from 1991

Chapter 2, Problem 97

(choose chapter or problem)

The numbers D of doctorate degrees (in thousands) awarded to female students from 1991 through 2012 in the United States can be approximated by the model

\(D=0.0743 t^{2}+0.628 t+42.61,\ \ \ \ \ 0 \leq t \leq 22\)

where t is the year, with t = 1 corresponding to 1991. (Source: U.S. National Center for Education Statistics)

(a) Use a graphing utility to graph the model.

(b) Use the zoom and trace features to find when the number of degrees was between 50 and 60 thousand.

(c) Algebraically verify your results from part (b).
