Question

Determine whether the relation is a function {(8, 0), (5, 4), (9, 3), (3, 8)}

Answer 1

It is a function. A function is a set of data points that do not repeat the an x value. We can clearly see that it does not repeat any numbers in the x value space.
8,5,9,3 are all different numbers, so the relation is a function.
Hope this helps!

Answer 2

Answer: It is a function.

Explanation:

By definition, a function is a relation in which the input value (the x value) has one and only one output value (value of y).

The first number of each ordered pair is the input value and the second number of each ordered pair is the output value.

As you can see, the inputs value of the relation given in the problem have one and only one output value. Therefore, you can conclude that the relation is a function.
