Trina brings 6 cubic yards of compost for planting the trees. Each trees need to be planted with 1/6 cubic yards of compost. Will there be enough compost to plant all the trees? If yes, how many extra trees can they plant? If no, how many trees can they plant?

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.
