The image contains exercises labeled "Latihan 1.4" with the following questions:

1. **Tentukan f(x) dari dua fungsi tunggal berikut:**
   - a. \( f(x) = 3x^2 + 2x - 5 \)
   - b. \( f(x) = x^2 - 4x + 1 \)

2. **Diberikan \( f(x) = 3x + 4 \) dan \( f(x) = 2x^2 + 7x \), tentukan fungsi g(x)!**

3. **Diketahui \( f(x) = 3x + 1 \) dan \( f'(x) = 2x \), tentukan fungsi f(x)!**

4. **Diketahui \( f(g(x)) = f(x) = 12x \).**
   - a. Temukan \( f(g(x)) = x^2 + 6 \).
   - b. Temukan fungsi \( f(x) \).

5. **Tentukan f(x) jika diketahui \( g(x) = 2 \) dan \( f(g(x)) = 2x^2 + 4x - 5 \).**

Would you like me to solve these questions or explain specific ones in detail? Here are 5 relative questions for further exploration:

1. How do you determine the derivative \( f'(x) \) of a given function \( f(x) \)?
2. What methods can be used to find a function \( g(x) \) when given its composite with another function \( f(x) \)?
3. How do you solve quadratic functions like the ones given in question 1?
4. What is the process for solving functions when both the function and its derivative are known, as in question 3?
5. How do you interpret the result of a composite function like \( f(g(x)) \)?

**Tip:** When working with composite functions, ensure you understand the relationship between the outer function \( f(x) \) and the inner function \( g(x) \) before proceeding to solve.
