functions and relations help

Draw the mapping diagram for the relation and determine whether it is a function or not. {(2, 4), (- 8, 0), (1, 5), (3, 1)} => Figure 2, Relation is not a function or Figure 4, Relation is not a function or Figure 1, Relation is ..

Determine whether the relation is a function or not. If so, find its domain and range. (1, - 1), (4, - 1), (- 7, - 1), (1, 1) => It is a function, domain: - 1 and 1, range: - 1, 4, - 7, and 1. or It is not a function. or It is a function, domain: - ..

Determine whether the relation is a function or not. If so, find its domain and range. (2, - 3), (3, - 3), (- 4, - 3), (2, 1) => It is a function, domain: - 3 and 1, range: - 2, 3, - 4, and 2. or It is not a function. or It is a function, domain: - ..

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

(a) (i) The relation should be one-one or many-one, and (ii) Every first element is mapped which means that every pre-image should have an image. (b) For graphs: Draw a line parallel to the y-axis. If it cuts the graph only in one point, then the graph represents a function. If..
