Obviously, 4.652 hours, right? This function is continuous because you can break down both temperature and time into the finest increments that you can measure. A continuous function allows the x-values to be ANY points in the interval, including fractions, decimals, and irrational values. The temperature will increase by 1 degree per hour this morning until noon. Despite the fact that you can measure a basketball players height to very small units (essentially continuous, just requiring better and better measuring equipment), shoe size is available (in the US) in 1/2 sizes (size 10, 10 1/2, 11, 11 1/2, 12, etc). The height of basketball players is roughly linear to their shoe size. The subject of graph theory had its beginnings in recreational math problems (see number game), but it has grown into a significant area of mathematical research, with applications in chemistry, operations research, social sciences, and computer science. So you can spend $2 and get 2 liters, $4 and get 4 liters, etc, but you cannot pay $3.82 to purchase 3.82 liters. graph theory, branch of mathematics concerned with networks of points connected by lines. Although the unit cost $1 per liter, it is not possible to purchase soda in any other increment than 2 liter bottles. Soda is on sale for $2 for a 2 liter bottle but that is the only size they have available. The number of people is discrete meaning you bring 1, 2, 3, 4, etc to the movies. But it is not possible to take 0.2 people to the movie. How many people get to see the movie? If continuous, it would be 3.2 people. AugA follow-up to the strong ring: the note 'Atiyah-Singer and Atiyah-Bott for simplicial complexes', a first attempt in the discrete.(local copy PDF). Discrete Mathematics is a branch of mathematics that is concerned with discrete mathematical structures instead of continuous. If the function were continuous, then we could say it takes 1.5 buses but there is no such thing as half a bus (at least it couldn't be driven to school. The answer, of course is 2 buses because buses are discrete. The domain of a function is what input values it can take on. Discrete means separate points that you cannot break into "in between" points.Įxample: There are 36 students how must ride the school bus. The definition of a function is as follows: A function takes any input within its domain, and maps this to 1 output.
