Question

Find the domain and range of the relation. Then determine whether the relation is a function

{(4, -7), (3,-7), (2,0), (4,0)}

Answer 1

Domain: {4, 3, 2}

Range: {-7,0}

This IS NOT a function

Explanation:

Since x=4 produces y=−7 and y=0, the relation (4,−7),(3,−7), (2,0),(4,0) is not a function.
