Arithmetic sequence

de_lolley — 2017-03-15 15:20:45 UTC

sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 5, 7, 9, 11, 13, 15 … is an arithmetic progression with common difference of 2.

Dependent variables

de_lolley — 2017-03-15 15:21:18 UTC

isolated on one side of an equation. Formally, a dependent variable is a variable in an expression, equation, or function that has its value determined by the choice of value(s) of other variable(s).

Function

de_lolley — 2017-03-15 15:21:22 UTC

s a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is thefunction that relates each real number x to its square x². ... Others are given by a picture, called the graph of the function.

Function rule

de_lolley — 2017-03-15 15:21:57 UTC

between two variables, often x and y, and for every value of x there is exactly one value of y. The x value is referred to as the independent variable and the y as the dependent variable.

Function table

de_lolley — 2017-03-15 15:22:08 UTC

is a rule that assigns a set of inputs to a set of outputs in such a way that each input has a unique output. A function table in math is a table that describes a function by displaying inputs and corresponding outputs in tabular form

Geometric sequence

de_lolley — 2017-03-15 15:22:21 UTC

is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio. For example, the sequence 2, 6, 18, 54, ... is a geometric progression with common ratio 3.

Independent variables

de_lolley — 2017-03-15 15:22:40 UTC

is x. The variable y is not independent since it depends on the number chosen for x.

Inequality

de_lolley — 2017-03-15 15:22:54 UTC

There are other special symbols that show in what way things are not equal. a < b says that a is less than b. a > b says that a is greater than b. (those two are known as strict inequality) a ≤ b means that a is less than or equal to b.

Linear function

de_lolley — 2017-03-15 15:23:04 UTC

has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. a is the constant term or the y intercept.

Sequence

de_lolley — 2017-03-15 15:23:21 UTC

is an enumerated collection of objects in which repetitions are allowed. Like a set, it contains members (also called elements, or terms).

Term

de_lolley — 2017-03-15 15:23:26 UTC

is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs.
