Jillian needs to determine the area of her garden so she can calculate how many roses she can plant. the width of the garden can be expressed as 2r and the length can be expressed as 6r^4+r^3-7r^2-8r

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.
