Domain & Range from Graphs - 10?s

Front

What is the definition of Domain in a graph?

Back

The set of all possible input values (x-values) for a function or relation.

Front

What is the definition of Range in a graph?

Back

The set of all possible output values (y-values) for a function or relation.

Front

How do you determine the domain from a graph?

Back

Identify the x-values that the graph covers; these values make up the domain.

Front

How do you determine the range from a graph?

Back

Identify the y-values that the graph covers; these values make up the range.

Front

What does it mean if the domain is 'All real numbers'?

Back

It means that any real number can be used as an input for the function.

Front

If a graph is defined only for x-values between 1 and 4, what is the domain?

Back

1 ≤ x ≤ 4.

Front

If a graph has points at y = -5, -1, 0, 1, and 5, what is the range?

Back

{-5, -1, 0, 1, 5}.

Front

True or False: The range can include negative values.

Back

True.

Front

What does it mean if a graph has a domain of -3 < x ≤ 3?

Back

x can take any value greater than -3 and up to and including 3.

Front

What is the significance of closed intervals in domain and range?

Back

Closed intervals include the endpoints, meaning those values are part of the domain or range.
