If a + h lies in the interval (a, b] and /(a) and /(b) are known, then you can use the average rate of change to approximate /(a + h). fath) s /(a)the J(b) - F(a) b - a Use an average rate of change over the interval [9, 25] to estimate the value of v 15. (Use decimal notation. Give your answer to two decimal places.) V15 = Use an average rate of change over the interval [9, 16] to estimate the value of v 15. (Use decimal notation. Give your answer to two decimal places.) V15 ~Which of the two preceding estimates is nearer the actual value of v 15? O over the interval [9, 25] O over the interval [9, 16] Based on the result of this exercise, do you think better results are obtained when using shorter or longer intervals? O The longer the interval, the better the approximation. The shorter the interval, the better the approximation. () The accuracy of the approximation does not depend on the length of the interval
