ANSWER

A. It is not a function

B. The second one

Step-by-step explanation

A. We want to determine if the relation is a function.

To do this, we have to examine the relation closely.

For a relation to be classified as a function, each value in the domain (the input values) must yield only one value in the range (the output).

From the relation given, we have that two numbers in the domain each give two numbes in the range.

That is:

4 -> 7 and 1

3 -> 8 and 9

Therefore, it is not a function

B. The correct option is the second one.

SInce, 3 and 4 each map out to two values, there is no need for repeating them.
