Question

Let $A=\{x,y,z\},B=\{a,b,c\}$ and $f:A\to B$ be defined by $f\left(x\right)=a,f\left(y\right)=b,f\left(z\right)=c$. This function is

• A. surjective but not injective
• B. injective but not surjective
• C. bijective
• D. none of these

Answer 1

The correct option is C bijective

Clearly function is one-one. Also Range and co-domain are same.
Hence given function $f$ is bijective.
