Question

Given is a strictly increasing function, f(x). Strictly increasing meaning: f(x)< f(x+1). (Refer to the example graph of functions for a visualization.)

Now, define an algorithm that finds the smallest positive integer, n, at which the function, f(n), becomes positive.

The things left to do is to:

Describe the algorithm you came up with and make it O(log n).

2. Strictly Increasing
Given a function, f(x), which is a strictly
increasing function, define an algorithm that
finds the smallest positive integer, n, for
which the function, f(n) becomes positive.
The challenge here is to solve this by
defining an algorithm that runs on O(log n)
time complexity.
