Function Definition: A one-to-one function, also known as an injective function, is a function where each x-value is paired with exactly one unique y-value, and no y-value is repeated. To determine which set of points does not represent a one-to-one function, we need to check if any y-value is repeated for different x-values in each set.Check First Set: Check the first set of points: {(9,8),(8,9),(5,6),(6,4),(1,7)}. We see that all y-values are unique for different x-values. Therefore, this set represents a one-to-one function.Check Second Set: Check the second set of points: {(9,6),(0,4),(3,5),(1,9),(5,6)}. We see that the y-value 6 is repeated for x-values 9 and 5. Therefore, this set does not represent a one-to-one function.Conclusion: Since we have already found a set that does not represent a one-to-one function, we can conclude the problem. However, for completeness, let's check the remaining sets.Check Third Set: Check the third set of points: {(1,5),(4,0),(8,2),(3,1),(7,8)}. We see that all y-values are unique for different x-values. Therefore, this set represents a one-to-one function.Check Fourth Set: Check the fourth set of points: {(2,7),(5,4),(4,0),(1,5),(3,2)}. We see that all y-values are unique for different x-values. Therefore, this set represents a one-to-one function.
