**Problem Statement:** Find the interval containing the solution of the equation: \[ g(x) = x^3 - 2x^2 - 4x + 3 = 0. \] **Explanation:** This problem involves finding an interval where the cubic function \( g(x) = x^3 - 2x^2 - 4x + 3 \) crosses the x-axis, which indicates the presence of a root. The task is to determine the x-values between which the solution(s) exist. This may involve analyzing the function via methods such as evaluating the function at different points, using graphical solutions or applying numerical methods like the Intermediate Value Theorem when certain conditions are met.

**Exercise: Application of Intermediate Value Theorem and Rolle's Theorem** Use the intermediate value theorem and Rolle's theorem to show that \( x^3 + 2x + k \) has only one root regardless of the value of \( k \). **Options:** - \( f(-k) > 0, \, f(k) > 0 \) - \( f(-k) < 0, \, f(k) > 0 \) - \( f(-k) < 0, \, f(k) < 0 \) - Not possible to determine --- This exercise requires applying two fundamental theorems from calculus to analyze the behavior of polynomial functions in relation to their roots. The intermediate value theorem suggests whether a function has a root in a given interval, while Rolle's theorem focuses on the behavior of derivatives to examine if multiple roots can exist in certain parts of the function’s domain. Your task is to use these theorems to determine the behavior of the function \( x^3 + 2x + k \).
