Answer & Analysis
Answer
A
Analysis
We can determine if the graph represents a function by applying 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:
For x < -3, the graph is a horizontal line, which means it has a single y-value for all x-values less than -3.
