Answer:
Domain: {5, 6, 7}
Range: {-3, -2, 0, 4}
The relation is a function
Step-by-step explanation:
Domain: the set of possible input values ([tex]x[/tex] values)
Range: the set of output values ([tex]y[/tex] values)
Therefore, from inspection of the table:
Domain: {5, 6, 7}
Range: {-3, -2, 0, 4}
A function is a relation where there should be only one output for each input (one-to-one, many-to-one)
If the relation has many outputs for one input, then it is not a function (one-to-many)
