a function is the composition of 2 functions

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}.Let f:AgB and g:AgB be two fu..

Let f : A g B and g : B g C be two functions. Let h: A g C be function such that h(x) = g(f(x)) h is called the composite of f and g, denoted by h = g o f. i.e., (g o f) (x) = g (f(x..

If range(f) C Dom(g), we define the composite function of g and f (gof) by gof(x) = g [f(x)] for all x A If range (g) C dom f, we define the composite function (fog) of f and g by fog (x) = f [g(x)] for all x..

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..

i. They protect the heart, large blood vessels and lungs. ii. They bear respiratory muscles, and play an important role in respiration. iii. The last two pairs of ribs protect the kidney..

We consider two sets A and B. We form the Cartesian Product, we form relations. From all the relations, we can select a few which satisfy the rule that each element of the set A is related to only one element of the set B. When a relation satisfies this rule, it is called a fuction. In..

Function - Any relation on A x B in which (i) no two second elements have a common first element and (ii) every first element has a corresponding second element is called a function.Any relation on A x B in which (i) no two second elements have a common first..

1. Constituent of carbonic anhydrase - zinc is essential for supply of CO 2 to the chloroplast and for the evolution of CO 2 during respiration. 2. Production of IAA (auxi..

1. Activator of enzymes like oxidases, peroxidases, dehydrogenase, kinases and dicarboxylases. 2. Maintenance of lamellar structure of chloroplast. 3. Essential for photolysis of water and evolution of oxyg..

1. Is a component of chlorophyll and magnesium pectate. 2. Essential for the formation of carotenoids. 3. Required by a large number of enzymes connected with phosphate transfer. 4. For binding of ribosomes. 5. Higher concentrations of Mg 2 + ions are found in seeds and growing ..
