In the formula I is called the subject of the formula.In the formula I is called the subject of the formula. To make 'P' the subject of the formula: P x T x R = 100 x I If make 'a' the subject of the formula. m(a + b) = a Cross multiplying. am + bm = a am -a = - bm Take terms containing 'a' to one ..

R = {(1, 1), (2, 3), (4, 6)}..

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 element and (ii) every first element has a corresp..

Every one element of A corresponds to more than one element of B. In example 3, one image has three pre-images. In example 4, one image has four pre-images. Therefore, many-one relations in examples 3 and 4 are many-one functions. Consider the following examples and note why these relations are NO..

The set of all the second elements of the ordered pairs of a function is called the rang..

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 this chap..

A function can be represented by the following methods: (i) An arrow diagram. (ii) Cartesian graph. (iii) Set-builder notatio..

The relation should be one-one or many-one, and Every first element is mapped which means that every pre-image should have an imag..

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

(1) One-one function (2) Many-one function (3) Onto function (4) Into function Let the relation be from set A to set ..
