I don't understand 2

1. Use geometry and properties of integrals to find V8. - 12 dx (Hint: Complete the square first, you can explore in Desmos.com, if you wish) y= 1 8 x - * 2 TT ( 4 ) 2 / 4 = 16TT / 4 = 4TT Y ? = 8 x _ x 2 4 Y 2 4 X - - 8 x = 0 8 x - x2 d x = 4+ y 2 + x 2 - 8 x + 16- 16+=0 4 2 + ( x - 4 ) = 14 Y 2 + ( x - 4) 2 = 42 1 = 4 A = Ur 3/4 2. Compute the area of the region bounded by the curves y = 3x and y = 23 -x. Hint: Use vertical cuts. (You can graph your functions in Desmos.com)
