To determine if a set of x and y values represents a function, we need to check if each x-value has a unique y-value. If every x-value is associated with only one y-value, then the set of values represents a function.
For example, let's consider the set of values: {(1, 2), (2, 3), (1, 4), (3, 5)}.
Here, the x-value 1 is associated with both y-values 2 and 4. Since multiple y-values are assigned to the same x-value, this set does not represent a function.
On the other hand, consider the set of values: {(1, 2), (2, 3), (3, 4), (4, 5)}.
Here, each x-value has a unique y-value. Therefore, this set represents a function since it satisfies the requirement of having a unique y-value for every x-value.
To determine whether a set of x and y values represents a function, you need to examine if there are any x-values that have more than one corresponding y-value.
