Vector valued and scalar valued functions

[Odyssey]

Hi what is the definition and meaning (geometric) of a vector valued and scalar valued function?

I read the definition in the textbook but I didn't quite get it.

Thank you.

The output of a "scalar function" is a scalar, that is just a number.

The output of a "vector function" is a vector.
