Question

What input and output have to be removed to make the relation a function?:

{(–9, –8), (–8, 4), (0, –2), (4, 8), (0, 8), (1, 2)}

(0,8)
(4,8)
(1,2)
(-9,-8)

Answer 1

(0,8)

Explanation:

The definition of function is that every input has an output and you will have to delete (0,8) because it’s repeating and if its repeating then it doesn’t fit in to the category of function.
