Q.

Consider the given statements

Statement I: If f(x) is bounded for x∈[a,b], then area bounded by curve y=f(x), x-axis, x=a and x=b is ∫abf(x) dx

Statement II: If f(x) is bounded and differentiable for x∈[a,b], then the area between y=f(x) and y=f-1(x) is equal to double the value of ∫ab|f(x)-x|dx

1 Only Statement I is true  
2 Only Statement II is true  
3 Both Statement I and II are True  
4 Both Statement I and II are false
