**Interactive Exercise: Sketching the Graph of a Piecewise Function**

**Instructions:**
Drag the points to sketch the graph of the given function. Determine whether \( f \) is continuous, piecewise continuous, or neither on the interval \( 0 \leq t \leq 3 \).

**Function Definition:**

\[
f(t) = 
\begin{cases} 
3t^2, & 0 \leq t \leq 1 \\
1 + t, & 1 < t \leq 2 \\
5 - t, & 2 < t \leq 3 
\end{cases}
\]

**Graph Explanation:**

The graph below represents the piecewise function \( f(t) \):

- **Interval \( 0 \leq t \leq 1 \):** The function is \( f(t) = 3t^2 \). This forms a parabolic curve starting at the origin (0,0) and ending at the point (1, 3).
  
- **Interval \( 1 < t \leq 2 \):** The function is \( f(t) = 1 + t \). This is a linear segment starting just above 2 (open circle at \( t = 1 \)) and ending at the point (2, 3).
  
- **Interval \( 2 < t \leq 3 \):** The function is \( f(t) = 5 - t \). This is another linear segment starting just below 3 (open circle at \( t = 2 \)) and ending at the point (3, 2).

**Visual Features:**

- **Solid Red Circles:** Indicate points of continuity where the function is defined and touches the graph directly.
- **Open Red Circles:** Indicate points where the function is not defined at that specific \( t \), implying a discontinuity at these points.

**Question:**
Using the graph and function properties, decide: \( f(t) \) is \( \_\_\_\_ \).

(Options: Continuous, Piecewise Continuous, Neither)

Explore how the function behaves at different intervals to classify its continuity.
