Bot GPT 4-o mini In order for the relation to be a function, each input (x-value) must be unique; that is, no two ordered pairs can have the same x-value.
In the set you provided: {(2, 8), (4, 5), (7, 3), (9, 0), (?, 6)}, the current x-values are 2, 4, 7, and 9.
The missing x-value is represented by "?". The only x-value provided that is already in the set of x-values is 7. Therefore, if we choose 7 for the missing x-value, we will have two pairs with the x-value of 7, which violates the definition of a function.
Thus, the missing x-value cannot be 7.
Final answer: 7
