Type the correct answer in the box.

x y

3 10

_ 20

In the table, the relation (x, y) is not a function if the missing value of x is __.

The missing value of x is 3

Step-by-step explanation:

Given Table:

x y

3 10

__ 20

The relation of x and y (x, y) is not a function.

Relation is function if it is one-to-one.

One-to-one means to different value of x to get different value of y.

If function is not a function then one value of x to get two different value of y.

For first value of x=3, y=10

For which value of x=?, y=20

x must be 3

x=3 to get y=20

The missing value of x is 3 because same of x we get two different value of y.
