Question
Let a function $f: A \rightarrow B$, where $A=\{1,2,3\}$ and $B=\{6,7,8\}$such that $a<b \Rightarrow f(a)<f(b)$,where $a \in A \& b \in B$.Then find the number of one-one function between $A$ to $B$.
Step 1
The function $f$ is defined such that if $a<b$, then $f(a)<f(b)$. This means that the function is strictly increasing. Show more…
