Problem #7: Let f(x) = 4, 0.2 x 1.8. Suppose that we approximate f(x) by the 3rd degree Taylor polynomial I;(x) centered at a = 1. Taylor's inequaltiy gives an estimate for the error involved in this approximation. Find the smallest possible value of the constant M referred to in Taylor's Inequality. Problem #7: Enter your answer symbolically, as in these examples
