Math vocab test. 3

A number sequence formed by adding a fixed number to each previous term to find the next term. The fixed number is called the common difference.

When a change in one quantity causes a change in a second quantity, A correllation between two quantities does not always imply it.

The difference between consecutive terms of an arithmetic sequence.

A graph that is unbroken

A number from -1 to 1 that tells you how closely the equation of the line of best fit models the data. Represented by the variable r.

A graph composed of isolated points

The possible values for the input of a relation or function

Expresses the nth term of a sequence in terms of n.

The process of predicting a value outside the range of known values.

A relation in which each element of the domain corresponds with exactly one element in the range.

A method for writing variables as a function of other variables.

The process of estimating a value between two known quantities

The most accurate trend line on a scatter plot showing the relationship between two sets of data

A function whose graph is a line. You can represent it with a linear equation.

A method used to calculate the line of best fit.

When y-values tend to decrease as the x-values increase, the two data sets have this.

When data with a negative association are modeled with a line, there is this.

When there is no general relationship between x-values and y-values.

No two elements of the domain map to the same element in the range.

When y-values tend to increase as the x-values increase.

When data with a positive association are modeled with a trend line.

The possible values of the output, or dependent variable, of a relation or function.

Defines the terms in a sequence by relating each term to the ones before it. It is composed of an initial value and a rule for generating the sequence.

Any set of ordered pairs

the difference between the y-value of a data point and the corresponding y-value of the model for the data set.

An ordered list of numbers that often forms a pattern

Any number in a sequence

Function maps each point of its graph to a new location

Transformation that shifts the graph of a function the same distance horizontally, vertically, or both.

A line that models the data in a scatter plot by showing the general direction of the data.
