The semicircular region bounded by the curve x = √9 - y² and the y-axis, is revolved about the line x = -4. The integral that represents its volume is V = = L a a = b= f(y) dy, where f(y) =

Find the domain and range of z= f(x,y)= ln(y-x^2). A. Graph the region in xy-plane that represents the domain.

Find the area of the region bounded by x=e^y, x=lny, the line y=2, and the x- and y-axes. Express the answer in exact form.
