State whether true or false the following relation is a func

State whether true or false. the following relation is a function. {(1, 0), (3, -2), (-6, 3), (-8, 0)} Answer/response: True False

Solution

True

the given relation is a function because there are unique x values like x=1,x=3 ,x=-6 and x=-8 for which we have different y .for x=1 we have y=0 and also for x=-8 we have y=0. (We can have same y for different x but we cannot have different y for same x )
