### Problem Statement

**3. Find the Laplace transform \( F(s) = \mathcal{L}\{f(t)\}(s) \) where**

\[
f(t) = 
\begin{cases} 
t^2 & \text{for } 0 \le t < 2 \\
4 & \text{for } t \ge 2
\end{cases}
\]

**You do not have to take the inverse Laplace transform.**

### Explanation

In this problem, you are asked to find the Laplace transform of a piecewise function \( f(t) \). The function \( f(t) \) is defined as follows:

- For \( 0 \le t < 2 \), \( f(t) = t^2 \).
- For \( t \ge 2 \), \( f(t) = 4 \).

The Laplace transform \( \mathcal{L}\{f(t)\}(s) \), often denoted as \( F(s) \), is a method to transform a time-domain function \( f(t) \) into a complex frequency-domain representation \( F(s) \). In this text, you are not required to determine the inverse Laplace transform.
