Inverse variation: a relationship between two variables in which the product is constant.
Constant of variation: the ratio between two variables in a direct variation or the product of two variables in an inverse variation.
Rational function: is any function which can be defines by a rational function.
Rational expression: Nothing more than a fraction whose numerator and denominator are polynomials.
Complex fraction: A fraction which contains a fraction in both numerator and denominator.
Parent Function for Simple Rational Functions: is the simplest function of a family of functions.
Simplifying Rational Expressions:A rational expression (or algebraic fraction) is a fraction with a polynomial in the numerator and and a nonzero polynomial in the denominator.
Multiplying Rational Expressions: simplify fractions to the best of your ability to cross multiply.
Dividing Rational Expressions:For dividing rational expressions, you will use the same method as you used for dividing numerical fractions: when dividing by a fraction, you flip-n-multiply.
Adding or subtracting with like denominators: The main rule of this game is that we can't do anything until the denominators are the same!We need to find something called the least common denominator (LCD)... It's really just the LCM of our denominators
Adding or subtracting with unlike denominators:The main rule of this game is that we can't do anything until the denominators are the same!We need to find something called the least common denominator (LCD)... It's really just the LCM of our denominators
Simplifying complex fractions: Find the least common denominator (LCD) of all fractions appearing within the complex fraction. 2. Multiply both the numerator and the denominator of the complex fraction by the LCD of the complex fraction from step 1
