Answer:


\{(-6, -4), (4, -8), (-6, 9), (1, -3)\}

Explanation:

Given


\{(5, -9), (6, -6), (-3, 8), (9, -6)\}


\{(-6, -4), (4, -8), (-6, 9), (1, -3)\}


\{(1, -1), (-5, 7), (4, -9), (-9, 7)\}


\{(8, -9), (-3, -6), (-4, 4), (1, -5)\}

Required

Which is not a function

An ordered pair is represented as:


\{(x_1,y_1),(x_2,y_2),(x_3,y_3),..........,(x_n,y_n)\}

However, for the ordered pair to be a function; all the x values must be unique (i.e. not repeated)

From options (a) to (d), option (b) has -6 repeated twice. Hence, it is not a function.
