Q34Multiple correct5 Marks16 Oct 2022Consider the following relations defined on the set of integers: R1={(x,y):x,y∈Z, y=x2−1}R_1=\{(x,y):x,y\in\mathbb{Z},\ y=x^2-1\}R1={(x,y):x,y∈Z, y=x2−1} R2={(x,y):x,y∈Z, ∣x∣+∣y∣=1}R_2=\{(x,y):x,y\in\mathbb{Z},\ |x|+|y|=1\}R2={(x,y):x,y∈Z, ∣x∣+∣y∣=1} Choose the correct option(s).AR1∩R2R_1\cap R_2R1∩R2 represents an injective function.BR2R_2R2 represents a relation but not a function.CR1R_1R1 represents a function.DR2R_2R2 represents a function.
