how relations become functions

Determine whether the relation is a function or not. If so, find its domain and range. {(1, - 2), (3, - 2), (- 5, - 2), (1, 1)} => It is a function, domain: {1, 5, - 3, 1}, range: {- 2, 1}. or It is not a function. or It is a function, domain: {- 1,..

Determine whether the relation is a function or not. If so, find its domain and range. (2, - 4), (5, - 4), (- 8, - 4), (2, 1) => It is not a function. or It is a function, domain: - 4 and 1, range: - 2, 5, - 8, and 2. or It is a function, domain: - ..

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..

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 th..

Every one element of A corresponds to one element of B. Every first element has a corresponding second element. One-one relations in examples 1 and 2 are called one-one functions. Every element of set A has one image in set B. {(1, 4), (2, 4), (3, 4), (4, 5)} Here, one image ..

The arrow diagram represents a relation from set A to set B. (i) Represent the relation in roster form. (ii) Is this relation a function? Give reason for your answer. (i) {(1, 2), (2, 4), (5, 2), (3, 10), (4, 10)} (ii) Yes it is a function. E..

Draw the mapping diagram for the relation and determine whether it is a function or not. {(3, - 1),(6, - 1),(3, - 2),(6, - 2)} => Figure 1, Relation is a function or Figure 2, Relation is not a function or Figure 4, Relation is a..

Determine whether the relation represented by the set of ordered pairs below is a function or not. (1, - 3), (4, - 3), (- 6, - 3), (1, 1). => It is not a function. or It is a function. or It is a function with same domain and range. or cannot be det..

Frank works as a sales person. He earns a salary of $425 and 4% commission on his monthly sales. Write a function rule that relates his total earnings to sales and find his earnings for the month, if his monthly sales are $4000. => $600 or $585 or $575 or $745..

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. (- 4, 2), (- 8, 5), (9, 5), (- 10, 7). => It is a function, domain: - 8, 9 and - 10, range: 2, 5 and 7 or It is a ..
