5.10 Find the maximum of the following function $f(x) = 1 - 8x + 2x^2 - \frac{10}{3}x^3 + \frac{4}{4}x^4 + \frac{4}{5}x^5 - \frac{1}{6}x^6$ Hint: $f'(x) = (1 + x)^2(2 - x)^3$ (a) Analytically. (b) By Newton's method (two iterations will suffice). Start at $x = -2$. List each step of the procedure. (c) By quadratic interpolation (two iterations will suffice). Start at $x = -2$. List each step of the procedure.
