1. Inverse Variation- An equation in the form xy=k, where k≠0.
2. Product Rule- If (x1, y1) and (x2, y2) are solutions to an inverse variation, then y1x1=y2x2
11-2
3. Rational Function- An equation in the form f(x)=p(x)/q(x), where p(x) and q(x) are polynomial functions and q(x) ≠0
4. Excluded Values- Any valunes of a variable that result in a denominator of 0 must be excluded from the domain of that variable.
5. Asymptote- A line that a graph approaches.
11-3
6. Rational Expression- An algebraic fraction with a numerator and denominator that re polynomials.
11-4 None
11-5 None
11-6
7. Least Common Multiple (LCM)- The least number that is a common multiple of two or more numbers.
8. Least Common Denominator (LCD)- The least common multiple of two or more numbers.
11-7
9. Mixed Expression- An expression that contains the sum of a monomial and a rational expression.
10. Complex Fraction- A fraction that has one or more fractions in the numerator or denominator.
11-8
11. Rational Equation- Equations that contain rational expressions.
12. Extraneous Solutions- Results that are not solutions to the original equation.
13. Work Problems- Rational equations are used to solve problems involving work rates.
14. Rate Problems- Problems in which an object moves at a certain speed or rate.
