Question

Determine the laplace transform of the figure shown below with a, b, and k as constraints.

The diagram is a graph representing a piecewise linear function \( x(t) \) with respect to \( t \).

- The horizontal axis is labeled as \( t \).
- The vertical axis is labeled as \( x(t) \).

Key Features:

1. **Graph Shape**: The graph is a symmetrical triangle.
   - It starts from the origin point (0,0).
   - It rises linearly to a peak point at \( (a, k) \).
   - It then decreases linearly back to the horizontal axis at point \( (b, 0) \).

2. **Points**:
   - The peak of the triangle is at time \( t = a \) and value \( x(t) = k \).
   - The base of the triangle runs from \( t = 0 \) to \( t = b \).

3. **Dashed Lines**:
   - A horizontal dashed line extends from the peak at \( (a, k) \) to the vertical axis, indicating the maximum value \( k \).
   - A vertical dashed line drops from the peak at \( (a, k) \) to the horizontal axis, indicating the time \( t = a \).

This type of graph is often used to represent a time-dependent process that grows to a certain level and then declines symmetrically, similar to a triangle wave.
