1. Locating Real Zeros of Polynomials
MAT 102 ~ College Algebra ~ Lesson 5.3

2. Rational Root Theorem
If f(x) is a polynomial of integer coefficients, then any rational root zero of f must be in the form of p/q, where p is a factor of a0 (last number) and q is a factor of the leading coefficient an

3. Use the rational root theorem to list all possible rational zeros, then locate actual zeros

6. Intermediate Value Theorem
If f(x) is a polynomial, and a and b are real numbers with a < b . If f(a) and f(b) differ in signs, then there is at least one point c, such that a < c < b and f(c) = 0. That is, at least one zero of f lies between a and b.

7. Show that f(x) has a zero between the given values and approximate that zero to the nearest tenth
