Question

If f(x+1)=2f(x) and f(1)=2 what is f(10)?

Answer 1

This is called a recursive function. Basically, if you pooped and then ate your poop and then pooped out your poop again, you would be a recursive function.

Just plug in poop until you get to f(10).

Answer 2

IT CAN BE EASILY SHOWN THAT F OF X EQUALS TWO TO THE X FOR ALL INTEGER X.
