Which of the following function is not onto? WebAn onto function is also called surjective function . How many onto functions are there? So, total numbers of onto functions from X to Y are 6 (F3 to F8). If X has m elements and Y has 2 elements, the number of onto functions will be 2 m -2. Explanation: From a set of m elements to a set of 2 elements, the total number of functions is 2 m .
