Question
The Intermediate Value Theorem can be used to approximate a root. The following is an example of binary
search in computer science. Suppose you want to approximate v8. You know that it is between 2 and 3. If you
consider the function f(x) = x² – 8, then note that f(2) < 0 and f(3) > 0. Therefore by the Intermediate
Value Theorem, there is a value, 2 <c< 3 such that f(c) = 0. Next choose the midpoint of these two
values, 2.5, which is guaranteed to be within 0.5 of the acutal root. f(2.5) will either be less than 0 or
greater than 0. You can use the Intermediate Value Theorem again replacing 2.5 with the previous endpoint
that has the same sign as 2.5. Continuing this process gives a sequence of approximations xn with x1 = 2.5.
How many iterations must you do in order to be within 0.015625 of the root?
