A function is a relation where there is only one output for every input. In other words, for every value of , there is only one value for .
A horizontal asymptote is a horizontal line that indicates where a function flattens out as the independent variable gets very large or very small. A function may touch or pass through a horizontal asymptote.
Ohm's Law states that a current through a conductor that connects two points is directly proportional to the potential difference between its ends. Consider , where is the voltage or the potential difference, is the current, and is the resistance of the conductor.
