Answer: [tex]Range:[/tex]{[tex]1,3,4,7[/tex]}Step-by-step explanation: We know that, by definition, the Domain is the set of all the x-coordinates of the ordered pairs and the Range is the set of all the y-coordinates of the ordered pairs. Therefore, given [tex]f=(2,3),(5,7),(5,4),(9,1)[/tex], you can observe that the set of all second elements of ordered pairs (the values of "y") is the following: {[tex]3,7,4,1[/tex]} Therefore, we can conclude that if [tex]f=(2,3),(5,7),(5,4),(9,1)[/tex] , then the range is: [tex]Range:[/tex]{[tex]1,3,4,7[/tex]}
