Double Integral of f(x,y)=x+y+2 is evaluated over the General Region between y=x^2-1 and y=1: part 1

The Double Integral of the function f(x,y)=x+y+2 is evaluated over the General Region between y=x^2-1 and y=1 where x is positive. A type 1 double integral is used. Calcplot3d is also used for visualization.
