Question: Which is used to determine if a relation is a function?
To determine if a relation is a function, you can use the vertical line test or examine the domain and range of the relation. Here are the methods commonly used to determine if a relation is a function:
1. Vertical Line Test: In this test, you visualize the relation graphically. If every vertical line you draw intersects the graph at a maximum of one point, then the relation is a function. Essentially, it means that each input (x-value) is associated with a unique output (y-value) and there are no vertical lines that cross the graph in multiple places.
2. Domain and Range Analysis: Another way to determine if a relation is a function is by examining the domain (set of all possible input values) and range (set of all possible output values). If each input in the domain is associated with only one output in the range, then the relation is a function. In other words, each x-value must have a unique corresponding y-value.
It's important to note that in a function, each input (x-value) can have only one output (y-value), but the same output can be associated with multiple inputs. However, if there is even a single input associated with multiple outputs, the relation is not a function.
