If f : R →R; f(x) = sin x + x, then the value of 
(f-1 (x)) dx, is equal to
Here we used the concept of integration and the inverse functions to solve the question. Finding an antiderivative of a function is the procedure known as integration. The process of adding the slices to complete it is comparable. The process of integration is the opposite of that of differentiation. So the final answer is
