Front

What is the domain of a function?

Back

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

Front

What is 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

Is the integer 5 part of the domain if it is included in the set of input values?

Back

Yes, if 5 is included in the set of input values, it is part of the domain.

Front

Is the integer 5 part of the range if it is included in the set of output values?

Back

Yes, if 5 is included in the set of output values, it is part of the range.

Front

What does it mean if the domain includes all real numbers between 0 and 8?

Back

It means that any number from 0 to 8 can be used as an input for the function.

Front

What does it mean if the range includes all real numbers between 0 and 20?

Back

It means that the function can produce any output value from 0 to 20.

Front

If the range includes all real numbers between 2 and 16, what does that imply?

Back

It implies that the function can produce any output value from 2 to 16.

Front

What is an example of a function with a domain of all real numbers between 0 and 8?

Back

An example is f(x) = x, where 0 ≤ x ≤ 8.

Front

What is an example of a function with a range of all real numbers between 2 and 16?

Back

An example is f(x) = 2x, where 1 ≤ x ≤ 8.

Front

How do you determine if a number is in the domain of a function?

Back

Check if the number is included in the set of input values defined for the function.
