Let's analyze each graph and equation:
- Graph A: This graph represents a hyperbola. The equation that matches a hyperbola is $$y = \frac{5}{x}$$. So, A matches with 1.
- Graph B: This graph represents a straight line with a negative slope. The closest equation is $$y = -\frac{x}{5} - 5$$. So, B matches with 3.
- Graph C: This graph represents a parabola opening upwards with its vertex below the x-axis. The equation that matches this is $$y = x^2 - 5$$. So, C matches with 2.
Therefore, the correct matching is:
