The Absolute Extreme Values on a Restricted Domain If the domain of f(x) = x 2 is restricted to [-2, 3], the corresponding range is [0, 9]. As shown below, the graph on the interval [-2, 3] suggests that f has an absolute maximum of 9 at x = 3 and an absolute minimum of 0 at x = 0.
Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e. a soil containing more than 85% sand-sized particles (by mass).
Sandstone is a sedimentary rock composed of sand-sized grains of mineral, rock or organic material. It also contains a cementing material that binds the sand grains together and may contain a matrix of silt-or clay-size particles that occupy the spaces between the sand grains.he grains of sand in a sandstone are usually particles of mineral, rock or organic material that have been reduced to sand size by weathering and transported to their depositional site by the action of moving water, wind or ice.
