Answer:

a) No, because one x-value corresponds to two different y-values.

Step-by-step explanation:

Let's find the coordinates from the table values.

(2, 1), (3,4), (3, 3), (4, 2), (5, 5)

Here the input 3 has two outputs 4 and 3

3 is associated with two numbers 4 and 3.

Therefore, it is not a function.

Answer: a) No, because one x-value corresponds to two different y-values.

Hope you will understood the concept.

Thank you.

Answer:

Choice A is correct.

Step-by-step explanation:

We have ordered pair in the table:

(2,1) (3,4) (3,3) (4,2) (5,5)

We have to explain is it a function or not ?

Function is a rule that gives each input a single output.

It is not a function because one x value correspond to two different y values.

It is shown from the table that the input 3 has two different output values that is 4 and 3.

Input 3 has two outputs 4 and 3.

Choice A is correct.
