fiNd the Matrix That Represents the Given Relation $$R ^ { 2 } \text {, where } R \text { is the relation on on } \{ 1,2,3,4 \} \text { such that } a R b \text { means } | a - b | \leq 1 \text {. }$$

Short Answer

find the matrix that represents the given relation. Use elements in the order given to determine rows and columns of the matrix.
- $$R ^ { 2 } \text {, where } R \text { is the relation on on } \{ 1,2,3,4 \} \text { such that } a R b \text { means } | a - b | \leq 1 \text {. }$$
