Find the Relative Maximum, Minumum, Zeros, and y-intercept

This graph represents a cubic polynomial function plotted on a Cartesian coordinate system. The x-axis and y-axis are both marked at integer intervals. The graph illustrates the behavior and key points of the function, which includes x-intercepts, y-intercepts, and a minimum point.

### Key Features:

1. **Intercepts:**
   - **Y-Intercept:** 
     - The graph intersects the y-axis at (0, 1).
   - **X-Intercepts:**
     - The graph intersects the x-axis at three points: 
       - (−0.532, 0)
       - (0.653, 0)
       - (2.879, 0)

2. **Extrema:**
   - **Local Minimum:**
     - The graph reaches a local minimum at the point (2, -3). This means that around this point, the function has a lower value than in the immediate vicinity, forming a trough.

### Graph Shape:
- The curve begins in the negative quadrant, rises to cross the x-axis at approximately −0.532, continues upward to the y-intercept at (0, 1), and crosses the x-axis again at approximately 0.653. 
- It then descends to a local minimum at (2, -3) before rising back up through the x-axis at about 2.879, continuing upward past the boundaries of the graph.

This cubic function demonstrates typical polynomial behavior, with turning points and intercepts that are key to understanding its graphical representation.
