Question

Determine whether each relationship is a function. State the domain and range of each relation.

Answer 1

Hello!

The answer is:

The relation is not a function

Domain: {3,2,1}

Range: {0,1,4,5}

Why?

Since the value 3 (domain) has two values at the output (0 and 1), the relation is not a function.  A function only exists when there is exactly a output value for each input, if there is more than one output for each input, the relation is not a function.

For this case, 3 (domain) has two outputs (0 and 1), so the relation is not a function.

Have a nice day!
