the domain is the set of x values, so {0, 2, 3}
the range is the set of y values, so {-4, -2, 1, -1}
by the way, you don't have a function, since the same x value of 3
yields more than one unique value of y
Review your definition of function.
There is no quick discernible rule for your set of points
{(3,-4),(3,-2),(0,1),(2,-1)}
what is the function?
what is the domain?
what is the range?
