Question

Determine the right table.

Answer 1

The correct answer option is A.

Explanation:

A process or a relation is said to be function such that each element of a set X is associated to only one single element of another set Y.

Here, in the given mapping diagrams, the set on the left represents x and the set on the right represent y.

Out of the given relation, the first mapping set does not represent a function as one value of x is associated with two values of y.

Answer 2

The correct option is 1.

Explanation:

A relation is called a function if there exist one value of y for each value of x.

In a mapping first set represent the value of x and second set represent the value of y.

In mapping 1, for
`x=-5`, the value of y is -4 and 3. For single of x there exist more than one value of y, therefore this relation is not a function.

In mapping 2 and 3, for all values of x, the value of y is unique. For single of x there exist only one value of y, therefore these relations are function.

Therefore mapping 1 does not represent a function. Option 1 is correct.
