Question
Use a graph to determine the domain and range of this relation.
- It is not a relation.
- Domain: {-4, -2, -1, 3}; Range: {-1, 0, 1, 2}
- Domain: {-1, 0, 1, 2}; Range: {-4, -2, -1, 3}
- It is not one-to-one
Hint:
A domain or region is a non-empty connected open set in a topological space
The correct answer is: It is not one-to-one
{(3, 1), (3, -1), (-1, 0), (-2, 1), (-2, 2), (-4, -1)}
Since more than one element in the domain maps to single elements in the range, the function is not one-to-one.
Range is a statistical measurement of dispersion, or how much a given data set is stretched out from smallest to largest
