Afarmer is building a grain silo for storage. he estimates that will need 256 cubic yards of storage. the grain silo will be shaped as a cube. how long should one side of the grain silo be? (recall that the volume of a cube is calculated by l3, where l is the length of one side).

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.
