Activity 6: Interpreting Graphs of Functions

A visual check to see if a graph represents a function;

• Mapping Diagram

• Table

• Vertical Line Test

• Set of ordered pairs

Check all that apply to the "X" value

• input

• domain

• range

• output

• independent variable

Check all that apply to the "Y" value

• f(x)

• dependent variable

• range

• output

• independent variable

Check all that apply to the following graph:

• Discrete

• Continuous

• Linear

• Not a function

• Function

Check all that apply to the following graph:

• Discrete

• Continuous

• Linear

• Not a function

• Function

A graph in which the points are connected and the domain and range are a set of real numbers with no breaks in between.

• Domain

• Continuous

• Range

• Discrete

A graph in which the data consists of individual points that are not connected by a line or curve.

• Domain

• Continuous

• Range

• Discrete

Which of the following represents the domain of the graph?

• $-3\le x\le8$

• $-4.5\le y\le2.5$

• $-3\le y\le8$
