Let's cut to the chase: I know this subject & how to teach YOU

f(x) is a function if for every input value "x" in the domain, there is
one, and only one, output value "y" in the range.
That is the purpose of the "Vertical Line Test" as mentioned by Kenneth S. 
A vertical line drawn through any point on the graph should touch the
graph in only one place.
