The correct Answer is:
To solve the problem, we need to find the value of \( g(f(2)) \) given the functions \( f(x) = e^x \) and \( g(x) = \frac{x}{2} \). ### Step-by-Step Solution: 1. **Calculate \( f(2) \)**: \[ f(2) = e^2 \] Here, we substitute \( x \) with \( 2 \) in the function \( f(x) \). 2. **Evaluate \( e^2 \)**: The value of \( e^2 \) is approximately \( 7.389 \). This is a constant value that can be found using a scientific calculator or a mathematical table. 3. **Substitute \( f(2) \) into \( g(x) \)**: Now we need to find \( g(f(2)) \), which is: \[ g(f(2)) = g(e^2) \] 4. **Calculate \( g(e^2) \)**: Using the function \( g(x) = \frac{x}{2} \), we substitute \( e^2 \): \[ g(e^2) = \frac{e^2}{2} \] 5. **Evaluate \( g(e^2) \)**: Substituting the approximate value of \( e^2 \): \[ g(e^2) = \frac{7.389}{2} \approx 3.6945 \] 6. **Final Answer**: Therefore, the value of \( g(f(2)) \) is approximately: \[ g(f(2)) \approx 3.6945 \] ### Summary: The value of \( g(f(2)) \) is approximately \( 3.6945 \).
