Answer:
0 onto functions
Step-by-step explanation:
Let the sets be
such that:
![n(A) = 3](https://tex.z-dn.net/?f=n%28A%29%20%3D%203)
![n(B) = 8](https://tex.z-dn.net/?f=n%28B%29%20%3D%208)
Required
The number of onto functions
The condition for onto functions is:
For there to be an onto function from set A to set B, the number of elements of B must be less than the elements in set A
Since n(B) > n(A) i.e. 8 > 3
Then, there can't be onto functions from A to B
