Domain and Range of Discrete and Continuous Graphs

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.

Front

What distinguishes a discrete graph from a continuous graph?

Back

A discrete graph consists of distinct, separate points, while a continuous graph is unbroken and can take any value within a given range.
