Let \(A=[x_1,x_2,x_3,x_4,x_5]\) and \(B=[y_1,y_2,y_3,y_4]\).

A function \(f\) be defined from \(A\) to \(B\).

If, \(f(x_1)=y_1\) **&** \(f(x_2)=y_2\),

then what is the number of onto functions defined from \(A\) to \(B\) ?

**Note:**

The figure (in the pic) is a rough one. :)

Wanna try more problems on functions ?
