Question 5 Not yet answered 5. Use forward, backward and centered difference approximation to estimate the first derivative of f(x) = 5x3 -0.5x2 +0.25x +1.6 at x=0.7, h=0.2. Also obtain second order derivative using central difference formula at x=0.85. Marked out of 10.00 P Flag question GO 1 A V B 1 I iii III HI C? ☺
