Domain Range Graphs

Front

What is the domain of a graph?

Back

The domain of a graph is the set of all possible x-values (inputs) for which the function is defined.

Front

What is the range of a graph?

Back

The range of a graph is the set of all possible y-values (outputs) that the function can produce.

Front

How do you determine the domain from a graph?

Back

To determine the domain, identify the x-values that the graph covers on the horizontal axis.

Front

How do you determine the range from a graph?

Back

To determine the range, identify the y-values that the graph covers on the vertical axis.

Front

What does it mean if a graph has a closed interval for its domain?

Back

A closed interval means that the endpoints are included in the domain, indicated by brackets [ ] in notation.

Front

What does it mean if a graph has an open interval for its domain?

Back

An open interval means that the endpoints are not included in the domain, indicated by parentheses ( ) in notation.

Front

What is the maximum point of a graph?

Back

The maximum point is the highest point on the graph, where the y-value is at its greatest.

Front

What is the minimum point of a graph?

Back

The minimum point is the lowest point on the graph, where the y-value is at its least.

Front

How can you find the maximum value from a graph?

Back

To find the maximum value, look for the highest y-coordinate on the graph.

Front

How can you find the minimum value from a graph?

Back

To find the minimum value, look for the lowest y-coordinate on the graph.
