two types of functions

>Relation from a set A to a set B is a subset of A x B. - A relation R on a set A is reflexive if a R a, " a A- A relation R on a set A is symmetric if a R b b R a. - A relation R on a set A transitive if a R b and b R c a R c. A relation R is said to be an equivalence relation on A if it is reflex..

Functions - Let A and B be two non-empty sets.Let A and B be two non-empty sets. A function f from A to B is an association of every element of A to an unique element in B. We write this as f : A g B. A is called the domain. B is called the co-doma..

Atmosphere, which means sunlight, temperature, wind, humidity etc. Edaphic, which means the physical and chemical properties of the soil, it's water and air content etc. These factors affect the distribution, number, metabolism and behaviour of the organis..

There are 2 types of nephrons based on their location. (a) Cortical (b) Juxtamedullary. The cortical nephrons lie in the cortex of the kidney and form about 80% of the nephrons. The juxta medullary nephrons have their Bowman's capsule very close to the function of the ..

Let f:AgB and g:AgB be two functions. Thus the composition of two functions f and g denoted by gof or fog is the function from A into C defined by gof = {(a,b) for some c B, (a,c) f and (c,b) g..
