Use appropriate Lagrange interpolating polynomials of degrees one, two, and three to approximate
each of the following:
f (8.4) if f(8.1) = 16.94410, f(8.3) = 17.56492, f (8.6) = 18.50515, f (8.7) = 18.82091

The data for Exercise 5 were generated using the following functions. Use the error formula to find a
bound for the error, and compare the bound to the actual error for the cases n = 1 and n 2.
f(x) = x In x
f (x) = x + 4.001lx? + 4.002r + 1.101
f(x) = x cos x - 2r2 +3x - 1
