Also, I need to find f^-1(x). Aaaah help!!

Thank you!

#12:

Prove this conjecture:

Let f(x) be a function defined on the positive integers such that:

f(x) = x/2 if x is even
f(x) = (3*x+1)/2 if x is odd

Now I proved all the previous ones, but I need inspiration on this one. My teacher will give me extra credit on a test if i solve it, so help please!

What's the difference between taxis and kinesis?
I understand that taxis is when an individual moves toward or away from the stimulus, why is that?

And in kinesis: it depends on how strong the stimulus is, and the individual can move in any direction and at any rate, am i right?

And can you all give examples?
