A formula of order 4 for approximationg the first derivative of a function f gives: f'(0) ~ 4.50557 for h = 1 f'(0) = 2.09702 for h = 0.5 By using Richardson's extrapolation on the above values, a better approximation of f'(0) is: 1.00177 0.17095 O This option This option 1.93645 0.97318 O This option O This option
