Chapter 2.4, Problem 88E
Electricity consumption. Refer to the data in Table 1.
- (A) Let x represent time (in years) with x = 0 corresponding to 2000, and let y represent the corresponding commercial sales. Enter the appropriate data set in a graphing calculator and find a
quadratic regression equation for the data. - (B) If y = C(x) denotes the regression equation found in part (A), find C(30) and C′(30), and write a brief verbal interpretation of these results. Round answers to the nearest tenth of a billion.
Table 1 Electricity Sales
