For function f(x) = x In x, let Xo = 1, x = 2, x = 3. (Round to 4 decimal places) a) Construct the Lagrange interpolation polynomial of degree two (call it P(x)) to approximate f(1.5). b) Also, use the error formula f (x) P(x) = f(n+)-(x - x) to find the error bound for If (1.5) - P (1.5)], compare this bound to the actual error of f (1.5) - P(1.5).
