Domain and Range Practice II

Front

What is the definition of 'Domain' in 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 'Range' in 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 represent the domain of a function using interval notation?

Back

The domain can be represented using interval notation, which uses brackets [ ] for inclusive endpoints and parentheses ( ) for exclusive endpoints.

Front

What does the notation (-3, 9] mean for a domain?

Back

It means that x can take any value greater than -3 and up to and including 9.

Front

What does the notation [-5, 7) mean for a domain?

Back

It means that x can take any value from -5 to 7, including -5 but not including 7.

Front

If a function has a domain of (-8, 8), what does this imply?

Back

It implies that the function is defined for all x-values between -8 and 8, but not including -8 and 8.

Front

What is the significance of identifying the domain of a function?

Back

Identifying the domain helps to understand the limitations and valid inputs for the function, which is crucial for solving problems.

Front

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

Back

The range can be found by identifying the lowest and highest y-values that the graph reaches.

Front

What does the notation (-7, 1] mean for a range?

Back

It means that y can take any value greater than -7 and up to and including 1.

Front

What is the relationship between domain and range in a function?

Back

The domain consists of input values (x-values), while the range consists of output values (y-values) that result from those inputs.
