The correct Answer is:
To analyze the statements given in the question, we will break down the definitions of even and odd functions, and then evaluate the validity of each statement step by step. ### Step 1: Understanding Even and Odd Functions - **Even Function**: A function \( f(x) \) is called even if \( f(-x) = f(x) \) for all \( x \) in the domain of \( f \). Examples include \( f(x) = x^2 \) and \( f(x) = \cos(x) \). - **Odd Function**: A function \( f(x) \) is called odd if \( f(-x) = -f(x) \) for all \( x \) in the domain of \( f \). Examples include \( f(x) = x^3 \) and \( f(x) = \sin(x) \). ### Step 2: Evaluating Statement I **Statement I**: "Integral of an even function is not always an odd function." - Let’s consider an even function, for example, \( f(x) = x^2 \). - The integral of \( f(x) \) is: \[ \int f(x) \, dx = \int x^2 \, dx = \frac{x^3}{3} + C \] - The function \( \frac{x^3}{3} + C \) is neither even nor odd because: - \( f(-x) = \frac{(-x)^3}{3} + C = -\frac{x^3}{3} + C \) which does not equal \( f(x) \) or \( -f(x) \). - Therefore, Statement I is **true**. ### Step 3: Evaluating Statement II **Statement II**: "Integral of an odd function is an even function." - Let’s consider an odd function, for example, \( f(x) = x^3 \). - The integral of \( f(x) \) is: \[ \int f(x) \, dx = \int x^3 \, dx = \frac{x^4}{4} + C \] - The function \( \frac{x^4}{4} + C \) is even because: - \( f(-x) = \frac{(-x)^4}{4} + C = \frac{x^4}{4} + C \) which equals \( f(x) \). - Therefore, Statement II is **true**. ### Conclusion - **Statement I** is true: The integral of an even function is not always an odd function. - **Statement II** is true: The integral of an odd function is indeed an even function. ### Final Answer Both statements are true, but Statement II is not a correct explanation for Statement I. ---
