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) that the function can accept.

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.

What does it mean if a function has a range of all real numbers?

Back

It means that the function can produce any value on the y-axis.
