The table time (z.) 1 2 3 4 5 6 infections (y = f(x)) 32 37 34 48 53 69 depicts the number of newly infected individuals with a contagious, airborne disease at intervals of 1 day over a period of 6 days. Here i=0, 1,2,...,5 and the quantities zo = 1 and yo 32, respectively, represent the end of the first day of testing for the disease, and number of positive tests conducted by the end of that day. (Note: z, represents the end of a testing day, where the values of z, are as tabulated, while y, represents the number of positive tests conducted by the end of day x..) Page 4 of 5 (a) Construct a forward difference table for the above data. (b) (i) Use the table presented in (a), along with Newton's forward difference formula, to approximate f(7) with a polynomial of degree 3, P₁(a). Start with a = 1. (ii) Estimate the error in the approximation in (b)(i).
