It is suspected that the high amounts of tannin in mature oak leaves inhibit the growth ofwinter moth (Operophtera bromata L., Geometridae) larvae that extensively damage thesetrees in certain years. Table 1 lists the average weight of a sample of larvae at times in thefirst 17 days after birth. The sample was reared on young oak leaves.[Information was taken from Burden, R.L and Faires, J.D., Numerical Analysis, 9h Edition]610 17x, time in daysy, average weight(mg) | 6.67| 17.33 42.67 30.1Table 1a) Obtain the Lagrange interpolating polynomial to approximate the average weight of thesample winter moth larvae for the data given in Table 1.
