Exploring Domain & Range in Discrete and Continuous Functions

What is the domain in a function?

• All the points on the graph

• All the second values

• All the first values or x-coordinates

• All the y-coordinates

How can you identify a discrete graph?

• It has arrows indicating infinity

• It contains points that are only integers and not connected by lines

• It includes values that are not integers

• It has connected lines or curves

Which notation is used to write the domain and range of a discrete graph?

• Curly brackets

• Parentheses

• Square brackets

• Inequality notation

What is the range of a function?

• All the x-coordinates

• All the first values

• All the second values or y-coordinates

• All the points on the graph

How do you write the domain of a continuous graph?

• Using inequality notation

• Using parentheses

• Using square brackets

• Using curly brackets

What does an arrow on a graph indicate?

• The graph is continuous

• The graph is discrete

• The graph goes to infinity

• The graph has a maximum value

How can you identify a continuous graph?

• It has no points

• It has connected lines or curves

• It has points that are only integers

• It has a limited number of points

What is the domain of a continuous graph with arrows indicating infinity?

• All positive numbers

• All negative numbers

• All integers

In a mapping diagram, what does it indicate if multiple x-values map to the same y-value?

• The graph is continuous

• The graph is discrete

• The graph has no domain

When listing the range of a function from a table, what should you do if a value repeats?

• List it at the end

• List it only once

• List it multiple times

• Ignore it
