A common type of implicit function is an inverse function. Not all functions have a unique inverse function. If g is a function of x that has a unique inverse, then the inverse function of g, called g , is the unique function giving a solution of the equation for x in terms of y. This solution can then be written as Defining g as the inverse of g is an implicit definition. For some functions g, g (y) can be written … WitrynaProbability, probability lecture videos, probability tricks, probability class 12, probability class 11, probability tutorialSsc cgl exam preparation, ssc, s...
