They are outputs of an operation or activity.
One or more (and it has two or more outputs).
It is a mapping which assigns one or more outputs to each set of one or more inputs. A relationship need not be a function.
By definition. If one input has more than one outputs then it is not a function.
No. If an input in a function had more than one output, that would be a mapping, but not a function.
They would have to have multiple outputs available on the CD/MP3 player that you have.
Don't have to. There are ff's with only one output.
One gate would be the NOT gate.
what is the 10 outputs of the computers
A function is any relationship between inputs and outputs in which each input leads to exactly one output. It is possible for a function to have more than one input that yields the same output.
No it does not have RCA Outputs.
I'm assuming the headunit has 2 sets of RCA outs - Front and Rear. If so, then one of your amps will need to have RCA outputs(sometimes called pass through) as well as inputs. Run an RCA cable from the "rear" outputs on the deck, into the inputs of the amp that has outputs. Now run a cable from the outputs on that amp to the inputs on your sub-amp.
many inputs one outputs
