Sort the following graphs into one of the two groups (function or not a function). Function Not a Function Sort the following ordered pairs and mappings into one of the two groups (function or not a function). Function {(0,-5), (-4,3), (3,4), (1,5)} {(-2,-5), (-1,3), (0,-1), (1,3), (2,-5)} {(-1,3), (-2,3), (-3,3), (-4,3)} Not a Function {(2,-6), (-5,5), (4,3), (2,5)} {(4,8), (4,9), (4,10), (4,11), (4,12)} Which of the following ordered pairs does not represent y as a function of x? {(1, 2), (3, 5), (5, 7), (7, 10)} {(-1, 2), (3, 5), (5, 5), (7, 5)} {(1, 2), (3, 5), (5, 7), (3, 10)} {(1, 1), (3, 1), (5, 1), (8, 1)} Which graph does not represent y as a function of x?
