Answer:
(1,3)
Step-by-step explanation:
we know that
A function is a relation from a set of inputs (independent variable) to a set of possible outputs (dependent variable) where each input is related to exactly one output
Looking at the graph
For x=1 -----> y=1 and y=-3
Is not a function, because each input value can have only one output value
therefore
To create a set of ordered pairs that represents a function, remove the point (1,1) or remove the point (1,3)
