Let a, b, c andd be four approximations of the fixed point p of function f such that a - f(a) = -0.0001023, f(b) - b = 0.0010123, f(c) - c= 0.000123 and d- f(d) = 0.00001023, then the best approximation of the fixed point p among these four values is %3D %3D %3D Select one: O a. a O b.c O c.b O d. d Given the following data in the form (x, f(x)): (0, 1), (0.1, 2), (0.2, 3), (0.3, 4), (0.4, 5), (0.6, 7). If we use the data and the two-point open Newton-Cotes formula (n 1) to approximate f(z) dz, then the approximation we get for this integral is 2.4.
