Domain and Range of Graphs

Front

What is the range of a graph?

Back

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

Front

How do you find the range of a graph?

Back

The range is found by reading the ends of the graph from bottom to top.

Front

What variable does the range of a function refer to?

Back

The range refers to the Y variable.

Front

How do you find the domain of a graph?

Back

The domain is found by reading the ends of the graph from left to right.

Front

What is the domain of the graph?

Back

The domain is the set of all possible input values (x-values) that a function can accept.

Front

What does the notation [-3, 1) mean?

Back

It means that the range includes -3 and goes up to, but does not include, 1.

Front

What does the notation (-∞, ∞) represent?

Back

It represents that the domain includes all real numbers.

Front

What is the difference between open and closed intervals?

Back

Open intervals do not include endpoints, while closed intervals do.

Front

If a graph has a range of (2, 5], what does this mean?

Back

It means the range includes all values greater than 2 and up to and including 5.

Front

What is the significance of the domain in a function?

Back

The domain determines the possible input values for which the function is defined.
