Solve the third one sketch plot

### Impulse Response and System Analysis

#### Problem 1:
**Objective:** Find the impulse response for \( 0 \leq n \leq 4 \). Determine if the system is FIR or IIR.

\[ y[n] = 3x[n] - 2x[n-1] + 5x[n-2] + 4x[n-3] \]

#### Problem 2:
**Objective:** Find the impulse response for \( 0 \leq n \leq 4 \). Determine if the system is FIR or IIR.

\[ y[n] = -\frac{2}{3} y[n-1] + 3x[n] \]

#### Problem 3:
**Objective:** Given the system and input function \( x[n] \), find the output \( y[n] \).

\[ y[n] = 2x[n] - x[n-1] \]

\[ x[n] = 3\delta[n] + 5\delta[n-1] - 2\delta[n-2] \]

### Explanation:

- **FIR (Finite Impulse Response) systems** have impulse responses that become zero after a finite number of steps. 
- **IIR (Infinite Impulse Response) systems** have impulse responses that do not become zero, continuing indefinitely.

For each system problem, determine the impulse response by using the given equations and assess whether the system is FIR or IIR based on the response behavior.
