Let A={1,2,3...,100} and R be the relation defined as '' is a cube number'' on A. write R as a subset A×A. also, find the domain and range of. |

Answer» A = {1,2,3,.....,100} R = {(a,b) ∈ A x A | b = a3} ∴ R = {(1,1),(2,8),(3,27),(4,64)} ∴ Domain of R is D = {1,2,3,4} & Range of R is RR = {1,8,27,64} |
