|
Function
|
a set of ordered pairs such that no two ordered pairs have the same first member.
|
|
Geometric Sequence
|
is a sequence of numbers in which each
term is obtained by multiplying the preceding term by the same number (common ratio). |
|
Exponentail function
|
an equation of the form f(x) = a · bx + k where a ≠ 0, b > 0,
b ≠1 and x is any real number , is called an exponential function with base b. |
|
FOIL method
|
an application of the distributive property used to multiply two binomials.
The product of the two binomials is found by multiplying the First, Outer, Inner, and Last terms. |
|
Graphs
|
a pictorial representation of some mathematical relationship. It can be a point on a
number line, which is a graph of a real number. |
|
Variables
|
A variable is a symbol on whose value a function, polynomial, etc., depends.
|
|
Constants
|
a symbol representing a value that doesn’t change
|
|
Polynomials
|
Sum and/or difference of terms: example: 3x – 2 and 4x2 -5x + 3
A polynomial with two terms is a binomial. A polynomial with three terms is a trinomial |
|
Linear Function
|
a function whose graph is a straight line. A linear function of x can be
written in the form f(x) = mx + b, where m and b are constants. |
|
Coefficient
|
the numerical part of a term, usually written before the literal part, as 2 in 2x or
2(x + y). Most commonly used in algebra for the constant factors, as distinguished from the variables. |
