Find the relation give the domain and range and indicate which are functions.
<(5,-2) (3,-2) (5,-1)>
in these ordered pairs the x value domain is the first and the y value is the range, second
Domain {5,3,5}
Range {-2,1}
is a relation but not a function as there are two y values {-2,-1} for one x value {5}
This relationship is not a function.
The domain value 5 is paired with two different range values.
domai={5,3}
range={-2,-1}
not a function as two elements of domain have same image in range set.
domain is (5,3,5)
range is (-2,-1)
but it is not a function since domain is repeated
