Draw a vertical line if the line hits more than one point on the graph then it is not a function.
If a vertical line, within the domain of the function, intersects the graph in more than one points, it is not a function.
To determine if a function represents a proportional relationship, you can use a table of values to check if the ratio of the output (y) to the input (x) remains constant. If the ratios are consistent, the relationship is proportional. Additionally, graphing the function will help you visualize the relationship; if the graph is a straight line that passes through the origin (0,0), then the function is proportional. If either the table or graph does not meet these criteria, the relationship is not proportional.

If a vertical line, within the domain of the function, intersects the graph in more than one points, it is not a function.
The horizontal line test is used to determine whether a function is one-to-one and if it had a inverse.
Two ways to determine whether the relation is a function is use a mapping diagram or use a vertical line test.
