Relations and Functions : Definitions

Select the domain and range of F. F = {(x, y ) | x + y = 10}.

Domain: {10} Range: {10} or Domain: All Real Numbers Range: All Real Numbers

If the relation is a function, list the domain and range. If the relation is not a function, choose "not a function". C = {(9, 1) (8, -3) (7, 5) (-5, 3)}

Domain: {9, 8, 7, -5} Range: {1, -3, 5, 3}

1. The domain set of C 2. The range set of E 3. The range and domain of F 4. The range and domain of P

1. {2} 2. { 3, 4, 5, 6, } 3. domain = range = {all real numbers} 4. domain = {all real numbers}: range = {y: y = 3}

Select either relation (if the set is a relation but not a function), function (if the set is both a relation and a function), or neither (if the set is not a relation).

Relation

Which of the following statements best represents the relationship between a relation and a function.

A function is always a relation but a relation is not always a function.

Select either relation (if the set is a relation but not a function), function (if the set is both a relation and a function), or neither (if the set is not a relation). A = {(1, 2) (2, 2) (3, 2) (4, 2)}

Function

Select either relation (if the set is a relation but not a function), function (if the set is both a relation and a function), or neither (if the set is not a relation). F = {(x, y ) | x + y = 10}
