What is the domain of the function shown in the table? a. (–2, 0), (–1, 1), (0, 2), (1, 3) b. {–2, –1, 0, 1} c. {0, 1, 2, 3} d. {–2, –1, 0, 1, 2, 3}

The point is given as (x,y). 
where x is the value of x-coordinate and y is the y-coordinate. 

So, from the table we have points that make up the domain. 
These are;

(-2,0), (-1,1), (0,2) and (1,3)

Most of the people don’t make the sense of taking it
