For #1 use inclusion/exclusion to figure the answer.If $A = \left\{1,2,3,4,5,6\right\}$ and $B = \left\{a,b,c,d,e\right\}$. Then Total no. of

$(1)$ onto function from $A$ to $B$

$(2)$ into function from $A$ to $B$

$(3)$ Constant function from $A$ to $B$

In #2 how is

For #3 think what it means to be a constant function.
