disscussion reply to the question asked from students minimum words count 50 each need in 20 hours

1: One thing about inverse functions you can usually tell where the numbers go because it undoes another function. I understood it even though it came through the way it did. 

Even though we all work with the same problem everyone seems to work it out their own way or has a different answer that's the crazy part. any thoughts?

2:Given f(x) = 3x - 2 and g(x) = x² - 1 can you find:

f(g(x)) =

g(f(x)) =?

3:What are one-to-one functions?  How do they apply the concept of the inverse function?
