You can put this solution on YOUR website! Find the domain and range of the relation and detrmine if its a function
(6,1),(-10,-4),(2,-1),(3,-8)
.
The domain are all the x values:
{6, -10, 2, 3}
.
The range are all the y values:
{1, -4, -1, -8}
.
And, it IS a function because there is a unique y-value for each x-value (vertical line test)
