Question

You have prizes to revea

Look at this mapping diagram:
Domain
Range
19
0
-19
16
Is this relation a function?
yes
no

Answer 1

Yes

Explanation:

The domain is {-19, 19}

The range is {0,16}

We can write as ordered pairs to obtain:

(-19,0), (19,16)

None of the first coordinates of the ordered pairs repeats.

Hence the relation represents a function.
