In this post we highlight the point that which graph is function and not a function.  If a vertical line intersects a graph in one point, it is the graph of a function. If a vertical line intersects a graph in more than one point, it is not the graph of a function.   READ MORE DEFINITIONS CLICK HERE

In this post we define inverse function and also provide an example to clear the concept of it. The inverse function of f denoted by f-1 is a function from Y onto X and is defined by x= f–1(y)  for all x in y if and only if as y=f(x) , for all x The set X of all possible input values is …
