Answer :
[tex]R_{f} =[/tex]{1, 2, 3, 4}
[tex]{(1, (2)), (2, (4)), (3, (1)), (4, (3))}[/tex]
[tex]{(1, (2)), (2, (4)), (3, (1)), (4, (3))}[/tex]
Range is the y-values.
The points are in the form:
(x, y)
So the y-values are:
[tex]\sf\boxed{\{\sf1, 2, 3, 4\}}[/tex]
The points are in the form:
(x, y)
So the y-values are:
[tex]\sf\boxed{\{\sf1, 2, 3, 4\}}[/tex]
