WebOn A Graph . So let us see a few examples to understand what is going on. When A and B are subsets of the Real Numbers we can graph the relationship.. Let us have A on the x axis and B on y, and look at our first example:. This is not a function because we have an A with many B.It is like saying f(x) = 2 or 4 . It fails the "Vertical Line Test" and so is not a function. WebSep 29, 2024 · When you define a function you need to specify what domain and codomain it has. The function cannot have this functional equation if the expression is not defined for a member of its domain (i.e. division by 0 ). So you did not specify a function, you specified an equation that the function f is supposed to satisfy.
