Final answer:
A subexponential time function is worse than polynomial time but better than exponential time. An example of a subexponential function is f(n) = 2^n.
Step-by-step explanation:
In mathematics, a function that is worse than polynomial time but better than exponential time is called subexponential time. One example of a subexponential time function is the Subexponential function, which is denoted as f(n) = 2n.
Let's compare the growth rates of subexponential, polynomial, and exponential functions with an example. If we evaluate each function for n = 10, we get:
- Subexponential: f(10) = 210 = 1024
- Polynomial: f(10) = 102 = 100
- Exponential: f(10) = 210 = 1024
As you can see, the subexponential function grows faster than the polynomial function but slower than the exponential function.
