WebExamples: Using a mapping diagram, determine whether each relation is a function. Using a vertical line test, determine whether the relation is a function. Make a table for f (t) = 0.5x + 1. Use 1, 2, 3, and 4 as domain values. Evaluate the function rule f (g) = -2g + 4 to find the range for the domain (-1, 3, 5). WebApr 8, 2024 · The different types of relations are as follows-. Empty Relation- When there are no relations between any elements of a set, the relation is said to be an empty relation. R=. Universal Relation- When all the elements in the set are related to each other, the relation is said to be a universal relation. R=A x A.
