Question

1. Is the relation a function? Why or why not? {(-3,-2),(-1,0), (1, 0), (5,-2)}

Answer 1

Answer:

Yes

Step-by-step explanation:

In a function, every input (x) should have a unique output (y).

There can be multiple x for a y, but not multiple y for one x

Answer 2

Answer:

yes, the given relation is a function.

Step-by-step explanation:

The given relation is

{(–3, –2), (–1, 0), (1, 0), (5, –2)}

A relation is called function if each element of the domain is paired with exactly one element of the range.

It means for each value of x there exist a unique value of y.

In the given relation for each value of x there exist a unique value of y.

Therefore the required solution is yes and this relation is a function.
