Find the area of the region enclosed by the curves x+y^2 = 0 and x+3y^2=2

ganeshie8 (ganeshie8):

start by drawing a rough sketch of both the given curves

ganeshie8 (ganeshie8):

notice that the curves are simple parabolas symmetrical along x-axis

ganeshie8 (ganeshie8):

x=-y^2 wud look like that its a parabola along x-axis, and faces left cuz of - sign before y^2

ganeshie8 (ganeshie8):

x=-3y^2+2 goes in positive x direction for 2 units, and stretches along x axis by a factor of 3
