The following chart shows the total annual support for the arts in a country by federal, state, and local government in 1995-2003 as a function of time in years (t = 0 represents 1995) together with the regression line. (Assume a = 1.45, b = 1.65, and c = 1.85.) (a) Over the period [0, 4] the average rate of change of government funding for the arts was less than the rate predicted by the regression line. greater than the rate predicted by the regression line. approximately equal to the rate predicted by the regression line. (b) Over the period [4, 8] the average rate of change of government funding for the arts was less than the rate predicted by the regression line. greater than the rate predicted by the regression line. (b) Over the period [4, 8] the average rate of change of government funding for the arts was less than the rate predicted by the regression line. greater than the rate predicted by the regression line. approximately equal to the rate predicted by the regression line. (c) Over the period [3, 6] the average rate of change of government funding for the arts was less than the rate predicted by the regression line. greater than the rate predicted by the regression line. approximately equal to the rate predicted by the regression line. (d) Estimate, to two significant figures, the average rate of change of government funding for the arts over the period [0, 8]. (Be careful to state the units of measurement.) How does it compare to the slope of the regression line? less than the slope of the regression line greater than the slope of the regression line approximately equal to the slope of the regression line
