Question

each picture shows how a mapping, f, maps elements of a domain onto a range. which mapping, f, is not a function?

Answer 1

The top left corner graph is not a function because a domain cannot go to two different range values.

Answer 2

Answer: The first one.

Step-by-step explanation:

• A relation between two set is said to be a function if each input has a single output.
• The set of input value is known the Domain of a function.
• The set of output is known as the Range of the function.

The first mapping of f is not a function because there are 2 output values for a single input vale of 3.

Hence, the first mapping f is not a function.

Rest of other mapping are function.
