Area bounded by the curves y=x3y=x^3, y=x+6y=x+6 and x=0x=0 is

Solution

✅ Correct Option: 3

The curves meet where x3=x+6x^3=x+6, i.e. x=2x=2. Between x=0x=0 and x=2x=2 the line lies above the cubic, so area =∫02(x+6−x3)dx=[x22+6x−x44]02=2+12−4=10=\int_0^2\left(x+6-x^3\right)dx=\left[\frac{x^2}{2}+6x-\frac{x^4}{4}\right]_0^2=2+12-4=10.
