STAAR Algebra 1 Domain and Range

Front

What is the definition of 'Domain' in a function?

Back

The domain of a function is the complete set of possible values of the independent variable (usually x) that will not cause any undefined behavior in the function.

Front

What is the definition of 'Range' in a function?

Back

The range of a function is the complete set of possible values of the dependent variable (usually y) that the function can produce based on the domain.

Front

How do you determine the domain of a function from a graph?

Back

To determine the domain from a graph, identify all the x-values that the graph covers. The domain includes all x-values for which there are corresponding y-values.

How do you determine the range of a function from a graph?

Back

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

Front

Back

It means that the function is defined for all x-values starting from 7 and extending to positive infinity.

Front

Back

It means that the function can produce y-values that are less than zero, but not including zero itself.

Front

Back

The graph will not include any points where x is less than or equal to 7.

Front

Back

The graph will not include any points where y is less than or equal to 0.

Front

What is the domain of the set of ordered pairs {(-7, 3), (-4, 0), (-1, -2), (3, 5), (5, 1)}?

Back

The domain is the set of all x-values: {-7, -4, -1, 3, 5}.

Front

What is the range of the set of ordered pairs {(-7, 3), (-4, 0), (-1, -2), (3, 5), (5, 1)}?

Back

The range is the set of all y-values: {3, 0, -2, 5, 1}.
