Question

Which ordered pair could be removed from the graph to

create a set of ordered pairs that represents a function?
(-4,2)
(-1,4)
(1,3)
(2, -3)

Answer 1

(1,3)

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)
