To determine if the graph represents a function, we can apply the vertical line test.

Vertical Line Test:  

1.If any vertical line intersects the graph at more than one point, then the graph does not represent a function.  

2.If every vertical line intersects the graph at exactly one point wherever it touches the graph, then the graph represents a function.

Analysis of the graph:

The description indicates:

For x < 0, the graph is a gradually decreasing straight line.

For x > 0, the grap...
