nsider the following equation. 3x4 - 8x3 + 2 = 0, [2, 3] (a) Explain how we know that the given equation must have a root in the given interval. Let f(x) = 3x - 8x3 + 2. The polynomial f is continuous on [2, 3], f(2) = -14 v < 0, and f(3) = > 0, so by the Intermediate Value 29 Theorem, there is a number c in (2, 3) such that f(c) = . In other words, the equation 3x4 - 8x3 +2 = 0 has a root in [2, 3]. (b) Use Newton's method to approximate the root correct to six decimal places. 2.345067 leed Help?
