39 arrow diagram function
The arrow diagram defines a function from A to B because each element of A has unique image in B. 2. Soln: a. The relation R 1 is not a function from X to Y because the element a of x has two images p and r in y but p ≠ r. b. An arrow diagram is defined as a process diagramming tool used to determine optimal sequence of events, and their interconnectivity. It is used for scheduling and to determine the critical path through nodes. Functions . A function is a one-to-one or many-to-one relation. Therefore the first and third arrow diagrams directly above represent functions. Each element in the domain must be mapped onto one and only one element in the range. The diagram in the middle is not a function because an element in the domain cannot be mapped on to two elements in Arrow diagram function
