1. The problem statement, all variables and given/known data Area enclosed by y=g(x), x=-3, x=5 and x-axis where g(x) is inverse function of ##f(x)=x^3+3x+1## is A, then find [A] where [.] denotes the greatest integer function. 2. Relevant equations 3. The attempt at a solution Honestly, I see no way to proceed here. Finding out the inverse is not possible here so I guess there is some trick to the problem. Any help is appreciated. Thanks!
