Question

Identify the domain and range of the relation. Use a

mapping diagram to determine whether the relation is
a function
((9,6), (3,8),(4,9.5), (9,2)}
​

Answer 1

Domain = {3,4,9}

Range = {2, 6, 8, 9.5}

Given relation is NOT a function.

Explanation:

Given relation is relation is ((9,6), (3,8),(4,9.5), (9,2)}.

Now we need to determine if given relation is a function or not.

We also need to find the domain and range.

((9,6), (3,8),(4,9.5), (9,2)}

​Domain is basically the collection of x-values

So Domain = {3,4,9}

Range is basically the collection of y-values

So Range = {2, 6, 8, 9.5}

Since given relation contains repeated x-value "9".

So the given relation is NOT a function.
