non domain settings

In the above definition of the function, set A is called domain..

The set of all the first elements of the ordered pairs of a function is called the domain..

Relations - A relation R is a non-empty sub-set of a cartesian product. A relation R is a non-empty sub-set of a cartesian product. A relation is a set of ordered pairs, i.e., R A x B where A and B are two non-empty sets. If R is..

Choose the function whose domain is the set of all reals except 0. => y = e x + | x | or y = cos x or y = - 1 x or y = | x |..

Relation - Consider the following sentences:Consider the following sentences: 42 is a multiple of 6. Line l is parallel to line m. 10 is greater than 7. In each case the first element is related to the last element by the relation in italics. The two elements named are members of two separate ..

A non-electrolyte does not provide ions in a solution and therefore current does not flow through such solution. The bulb in the given set up does not glow (Fig.4.6). Some examples of non-electrolytes are: alcohol, carbon tetrachloride, carbon disulphid..

Representation of a Relation - (i) Roster form(i) Roster form (ii) Set builder form (iii) By tables (iv) Arrow diagram (v) By graphs (i) Roster form: The ordered pairs are listed, R = {(2, 1), (4, 2), (6, 3), (8, 4), (10, 5)} Where A = {1, 2, 3, 4, 5} and R means 'is twice' in A x A xRy m..

Analyse the given data and make a proper choice of scale for time and distance. Plot the points. Join the point..

Determine whether the relation represented by the set of ordered pairs below is a function. Give the domain and range, if it is a function. (2, 3), (7, 8), (8, 8), (9, 9). => It is a function, domain: 7, 8 and 9, range: 3, 8 and 9 or It is a function, domain:..

Determine whether the relation represented by the set of ordered pairs below is a function. Give the domain and range, if it is a function. (40, - 42), (40, - 43), (41, - 44), (42, - 45). => It is a function and the domain is 40, 43 and 45, range: - 42, - 43, - 44 and ..
