rational function

a function which is the ratio of 2 polynomials

Asymptote

An imaginary line on a graph that acts as a boundary line.

vertical asymptote

comes from a factor in the denominator that doesnt cancel out

horizontal asymptote

a line that the curve approaches as x goes to infinity but never reaches

Linear Function

y = mx + b

Quadratic Function

a function that can be written in the form f(x)=ax^2+bx+c, where a, b & c are real numbers and a is not equal to zero

Absolute Value Function

any f(x) = | x |

Exponential Function

y = ab^x

square root function

Rational Expression

an algebraic fraction whose numerator and denominator are polynomials

multiplying rational expressions

P/Q x R/S = PR/QS ; 1. factor 2. multiply 3. and simplify

dividing rational expressions

P/Q / R/S = P/Q x S/R = PS/QR ; 1. factor 2. opposite reciprocal 3. multiply 4. and simplify

divide a polynomial by a monomial

use distributive property to divide each term of the polynomial by the monomial

divide a polynomial by a binomial

use long division and align terms by their degrees; for each missing power, add a term into dividend with 0 as its coefficient

any value that makes the bottom of a rational function equal zero

extraneous root

a solution to a transformed equation that is not a solution of the original equation

rational equation

an equation in one variable containing one or more rational expressions

reciprocal

One of two numbers whose product is 1; it is also called multiplicative inverse.

reduced form

most simpliest form

Domain

Range

The difference between the greatest number and the least number in a set of data.

slant asymptote

occurs when the degree of the top is higher than the degree of the bottom
