Algebra Module 3 Vocabulary

A function whose domain values include all decimals/fractions between whole numbers creates an infinite series of points that connect to form a line, or unbroken curve. This function is called a _________________.

• relation

• one-to-one function

• discrete function

• continuous function

An interval is ____________ where the function values are getting smaller, and the graph is moving in a downward direction.

• increasing

• decreasing

• constant

• negative

The _____________ is usually labeled as the y values on the graph. It's values change because of the change in the other variable.

• dependent variable

• independent variable

• domain

• zero

A _________________ has only whole domain values, with no valid data between them, and creates a graph that is a series of points (a scatterplot).

• vertical line test

• linear function

• discrete function

• continuous function

This graph does not represent a function because it fails the _________________.

• vertical line test

• y-intercept

• mapping

• end behavior

The first set of numbers in the ordered pairs is called the ____________.

• scale

• mapping

• range

• domain

The ________________ of a graph describes how the function values are changing at the negative and positive extremes of the domain (the left side and the right side of the graph).

• scale

• end behavior

• relative maximum

• line symmetry

The relative minimum and relative maximum values on a graph, showing locations of high and low values of the function, are called the ____________.

• end behavior

• domain

• extrema

• range

A _____________ is a relationship between input and output values, where every input has exactly one output value paired with it. This means that every domain value has exactly one range value associated with it.

• relation

• function

• mapping

• dependent variable

When the range values in a function are written in the form f(x), instead of y, the form is called __________________.

• function notation

• multiplication form

• confusing notation

• input-output form
