What's the rule for 830 823 817 812 808​

Each time you subtract one less then before

Step-by-step explanation:

I know this because from 830 to 823 they subtracted by 7 and then from 823 to 817 they subtracted by 6 so it keep going down the line.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
