Front

What is the definition of Domain in a graph?

Back

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

How do you determine the domain from a graph?

Back

To determine the domain from a graph, identify the x-values that the graph covers. Look for the leftmost and rightmost points of the graph.

If a graph has a domain of -8 < x < 5, what does this mean?

Back

This means that the function is defined for all x-values greater than -8 and less than 5.
