Topic #15: Domain and Range
A relation is a set of 1 or more
ordered pairs (x,y). The domain is
the set of all of the x coordinates.
The range is the set of all of the y
coordinates.
The domain and range can also be
determined from an equation.
Find the range of y  x if the
domain is 2.
2
The domain and range can also be
determined from a graph.
To find the inverse of a relation,
simply switch the x and y values.
Find the inverse of the relation
(2,0), (3, 1), (4, -6).
(0,2), (1, 3), (-6, 4)
