central difference approximation write a script which for a vector of increasingly smaller values of h computes approximations of f ′ (2) in matlab

f(x) = 98x^4 + 9x^3 + 5x^2 - x + 25 using the forward, backward and centered difference approximation methods, calculate the third derivative of this function in matlab

how to differentiate v(t) = 9.2 when t = 20 in matlab
