How many functions, onto, and one-to-ones?
Please help. I have been working on the following problem:
How many functions are there from http://brevardcc.angellearning.com/A...008_003780.gif, a set with two elements, to http://brevardcc.angellearning.com/A...024_884456.gif, a set with three elements?
How many of these functions are one-to-one?
How many are onto?
I get 9 functions, 6 one-to-one and 0 onto. Is this right?
Re: How many functions, onto, and one-to-ones?
Each of those answers is correct.
