Which relation does not represent a function? a. {(3, 0)}, {(0, 3)}. b. {(6, -2), (5, -2)}. c. {(3, 4), (3, 5)} d. {(5, 5), (-5, -5)}. e. {(1, -2), (-2, 1)}

Relation C does not represent a function

Mathematically  a simple function with one variable is defined as a  

so for each independent value of x  as input we get a value of  y in the output.

In other words , a function is a mapping of y values for unique value of x variables and hence for each unique x a function maps to value of y.

A function should not contain repeating values of x .

hence by observing the given data of the form we can conclude that Option C is  does not represent a function as x values are same.
