The correct Answer is:
To solve the given question, we will analyze both statements step by step. ### Step 1: Analyze Statement 1 We need to determine if there is a value of \( k \) such that the equation \[ x^3 - 3x + k = 0 \] has a root between 0 and 1. ### Step 2: Define the Function Let's define the function: \[ f(x) = x^3 - 3x + k \] We want to find \( k \) such that \( f(x) = 0 \) has a root in the interval \( (0, 1) \). ### Step 3: Evaluate the Function at the Endpoints We will evaluate \( f(x) \) at the endpoints of the interval: 1. Calculate \( f(0) \): \[ f(0) = 0^3 - 3(0) + k = k \] 2. Calculate \( f(1) \): \[ f(1) = 1^3 - 3(1) + k = 1 - 3 + k = k - 2 \] ### Step 4: Apply the Intermediate Value Theorem For \( f(x) \) to have a root in the interval \( (0, 1) \), \( f(0) \) and \( f(1) \) must have opposite signs. This gives us the conditions: - \( f(0) = k \) - \( f(1) = k - 2 \) We need: \[ k \cdot (k - 2) < 0 \] ### Step 5: Solve the Inequality The product \( k(k - 2) < 0 \) implies that \( k \) must be between the roots of the equation \( k(k - 2) = 0 \), which are \( k = 0 \) and \( k = 2 \). Therefore, the solution to the inequality is: \[ 0 < k < 2 \] ### Step 6: Conclusion for Statement 1 Thus, there exists a value of \( k \) (specifically any \( k \) in the interval \( (0, 2) \)) such that the equation \( x^3 - 3x + k = 0 \) has a root between 0 and 1. Therefore, Statement 1 is **true**. ### Step 7: Analyze Statement 2 Statement 2 states that between any two real roots of a polynomial, there is a root of its derivative. This is a direct consequence of Rolle's Theorem, which is a fundamental theorem in calculus. Therefore, Statement 2 is also **true**. ### Final Conclusion - Statement 1: True - Statement 2: True

To solve the given question, we will analyze both statements step by step. ### Step 1: Analyze Statement 1 We need to determine if there is a value of \( k \) such that the equation \[ x^3 - 3x + k = 0 \] has a root between 0 and 1. ...
