Question

Consider the following table:
Does the table represent a function? why or why not

A.The table represents a function because each element in the range is associated with exactly one element in the domain.

B.The table does not represent a function because each element in the domain is associated with exactly one element in the range

C.The table represents a function because each input has exactly one output.

D.The table does not show a function because each output does not have exactly one input.

Answer 1

D.The table does not show a function because each output does not have exactly one input.

Answer 2

Answer:

The correct option C.

Step-by-step explanation:

If for each input there exist a unique output, then the relation is called function.

According to the given table,

y = 7 at x=-2

y = 4 at x=-1

y = 3 at x=0

y = 4 at x=1

y = 7 at x=2

Here for each input i.e., x, it has a unique output i.e., y.

Therefore the table represents a function because each input has exactly one output and option C is correct.
