Jayden Dougherty · Answer 1

The domain is the numbers that you can use, normally the x values

(x, y)

so just list all the first numbers in each pair, ignore repeats

so

-3,5,-9,7,6

and people like to order them so

D=[-9,-3,5,6,7]

Kevin Decker · Answer 2

If I am not mistaken the domain should be [-3, 5, - 9, 7, 6].
