Domain and Range from a Graph

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 (input) for which the function is defined.

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 (output) that results from the function.

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

Back

The domain can be determined by identifying all the x-values that the graph covers.

Front

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

Back

The range can be determined by identifying all the y-values that the graph covers.

Front

What is the domain of the function represented by the graph that starts at x = -4 and goes to x = 1?

Back

The domain is (-4, 1].

Front

What is the range of the function represented by the graph that goes from y = -4 to y = 9?

Front

What is the domain of a function that is defined for all real numbers?

Back

Front

What is the range of a function that outputs values from 0 to infinity?

Back

Front

If a function has a range of [10, 25], what does this indicate about its outputs?

Back

This indicates that the outputs of the function can take any value from 10 to 25, inclusive.

Front

What does it mean if a function has a domain of (0, 45000]?

Back

This means that the function is defined for all values greater than 0 and up to and including 45000.
