Consider the region D bounded by x=y2-1 and x=1-y22.Write down a pair of inequalities on x and y that describes D.(For example, if I wanted to write down the inequalities for the region beneath y=x, above y=0 and to the left of x=1, I would use 0x1 and 0yx. I could instead use 0y1 and yx1.)Find the area of D.Find the volume of the solid under the graph of the function f(x,y)=xy+1 and above the region D.
