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).
What is Loam? The technical definition: Loam is soil that contains: less than 52% sand, 28 - 50 % silt, and; 7 - 27% clay; However if we had to measure that out every time we made a garden, there would be far fewer gardens. Basically loam is a soil comprised of almost equal amounts of sand and silt and a little less clay. Of the three components, sand particles are the largest. Sand does not hold onto moisture, but it provides good aeration. On the opposite end, clay particles are much smaller and easily compact.
