The domain for s, the independent variable, is all positive numbers. The range for S, the dependent variable, is also all positive numbers.

Independent variable is s because you are free to choose any side length, and with that choice you can compute the cube's area. Variable s is the INPUT, variable A is the OUTPUT.

This function is continuous.

It's rather important to understand (and remember) these fundamental concepts.

As a coping tactic, I suggest that you pay greater attention to your math lecture and when reading the textbook. And as soon as you do not understand something, ask a question in class so that the teacher can do his or her job and you will be recognized as a student interested in learning.
