Identify which of the given ph represents a function. 2+ 1+ -14 2+
Answer (1)
Answer:To determine if the given set of points represents a function, we need to check if each input (x-value) corresponds to exactly one output (y-value).The given points are:(2, 1), (2, -1), and (4, 2)Since the x-value 2 corresponds to two different y-values (1 and -1), this set of points does not represent a function.A function requires that each input (x-value) maps to a unique output (y-value). In this case, the input 2 maps to both 1 and -1, violating the definition of a function.
