find volume that is under z = 4x and over area D that is being blocked by y=x^2 y=0 and x=1
for y = 0 x must be 0 because y = x^2
so x will go from 0 to 1
y will go from 0 to x^2
but what about z? Will it go from 0 to 4x or should I say
z = 4x
y = x^2
that means y = z^2/16 => z = +/-4y
so z will be from -4y to 4y
here are the integrals
