(Solved): Using the same function: f(x) Estimate the first derivative at x = 0.5 using step sizes h= 0.5 ...



Using the same function: 
f(x) Estimate the first derivative at x = 0.5 using step sizes h= 0.5 and h = 0.25. Then, using Equation D, compute a best estimate using Richardson's extrapolation.
Remember the true value f'(0.5) = -0.9125, to calculate the relative error

f(x) = -0.1.x4 – 0.15x3 – 0.5x² – 0.25x + 1.2,
