Domain and Range Linear graphs, tables, and ordered pairs

Front

What is the definition of the domain of a function?

Back

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

Front

What is the definition of the range of a function?

Back

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

Front

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. The domain includes all x-values for which there are corresponding y-values.

Front

How do you determine the range from a graph?

Back

To determine the range from a graph, identify the y-values that the graph covers. The range includes all y-values that correspond to the x-values in the domain.

Front

What is the domain of the function defined by the set of ordered pairs {(1,2), (3,4), (5,6)}?

Back

The domain is {1, 3, 5}.

Front

What is the range of the function defined by the set of ordered pairs {(1,2), (3,4), (5,6)}?

Back

The range is {2, 4, 6}.

Front

If a function has a domain of x ≥ 0, what does this mean?

Back

This means that the function is defined for all x-values that are 0 or greater.

Front

If a function has a range of y ≤ 5, what does this mean?

Back

This means that the output values of the function can be any value less than or equal to 5.

Front

What is the domain of the function f(x) = 1/x?

Back

The domain is all real numbers except x = 0.

Front

What is the range of the function f(x) = 1/x?

Back

The range is all real numbers except y = 0.
