To determine which graph does not represent a function based on graph:

 

A. This graph is a cubic function. Cubic functions are typically smooth curves that can represent functions because each x value corresponds to exactly one y value. So, this graph represents a function.

 

A. This is a straight line passing through the origin. A straight line passes the vertical line test as it intersects any vertical line at most once. Therefore, this graph represents a function.

 

B. This describes two lines. Each of these lines individually represents a function because they pass the vertical li...
