I need help with part c which says use the best fitting function from part a to predict the period of a pendulum having a length of 5 ft.

A simple pendulum swings back and forth in regular time intervals. Grandfather clocks use pendulums to keep accurate time. The relationship between the length of a pendulum L and the period (time) T for one complete oscillation can be expressed by the function L = KT", where k is a constant and n is a positive integer to be determined. The data in the table were taken for different lengths of pendulums. Complete parts a through e below Click the icon to view the table. a. Find the values of k for n = 1, 2, and 3, using the data for the 4-ft pendulum. n K 1.802 2 812 .366 (Simplify your answers. Round to three decimal places as needed.) b. Use a graphing calculator to plot the data in the table and to graph the function L = KT" for the three values of k (and their corresponding values of n) found in part a. Choose the correct graph below. Each graph is displayed in a [0,3] by [0,5] viewing window. JA. OB. C. OD. O a Which function best fits the data? A. The function corresponding to n = 2 best fits the data. O B. The function corresponding to n = 3 best fits the data. O C. The function corresponding to n = 1 best fits the data. O D. None of the three functions fit the data
