# Answer on Integral Calculus Question for Rodel john

Question #4597

find the area bounded by the y² = 2x, y = x - 4.

Expert's answer

Let's transform our system:

x = y

and change variables:

y = x

Let’s find the points of interception: x

S= Integral(x+4-x

x = y

^{2}/2, x = y +4;and change variables:

y = x

^{2}/2, y = x +4.Let’s find the points of interception: x

^{2}/2=x+4x^{2}/2-x-4=0 x=4 or x=-2S= Integral(x+4-x

^{2}/2)dx |_{x=-2}^{x=4}=(x^{2}/2+4x-x^{3}/6) |_{x=-2}^{x=4}=18Need a fast expert's response?
