The exponential distribution has a single scale parameter λ, as deﬁned below. Deﬁnition 5.2 A continuous random variable X with probability density function f(x)=λe−λx x >0 for some real constant λ >0 is an exponential(λ)random variable. To find 2^x functions and factorial functions, the trick is to simply try dividing by f(n-1) for all functions which grow faster than polynomial time. That will do the trick. Dividing by f(n-1) maps n! to n and a^x to a allowing you to get a quick clear solution which you can output extremely efficiently. Given two points, write y=mx+b.
