RELATIONS AND FUNCTIONS: DEFINITIONS

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

Domain: All Real Numbers Range: All Real Numbers

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.

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}

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). input -1 0 -1 -8 9 output 0 1 2 4 8

relation

Match the following.

1. the domain set of C = {( 2, 5), (2, 6), (2, 7)} 3 domain = range = {all real numbers} 2. the range set of E = {(3, 3), (4, 4), (5, 5), (6, 6)} 1 {2} 3. the range and domain of F = {(x, y ) | x + y =10} 4 domain = {all real numbers}: range = {y: y = 3} 4. the range and domain of P = {(x, y) | y = 3} 2 {3, 4, 5, 6}
