Brief review of the lecture
The Intermediate Value Theorem states that every function
which is continuous over an interval of numbers has the intermediate
value property over that interval. The intermediate value property
over the interval [a,b] states the following: if the number M
is caught between f(a) and f(b), then there is a number c in the
interval [a,b] such that f(c)=M.
This useful theorem is important in isolating the roots of
a polynomial and of other continuous functions. If we find that for
polynomial p, p(a) is negative and p(b) is positive, then the
theorem states that p has a root between a and b.
The next topic is differentiation. We discussed and showed
examples of the use of the four step process for calculating a
derivative. It is important to practice this process.
