The area bounded by the parabola \(y=x^2-3x\) with \(y \leq 0\) is
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → \(\frac{9}{2}\)
Points where $y=0$
$⇒x^2-3x=0$
$⇒x(x-3)=0$
$⇒x=0\,or\,x=3$
$A=\int\limits_0^3(-(x^2-3x))dx$ [Absolute value of y]
$=\int\limits_0^3(3x-x^2)dx$
$=\left[\frac{3x^2}{2}-\frac{x^3}{3}\right]_0^3$
$=\left[\frac{27}{2}-\frac{18}{2}\right]=\frac{9}{2}$ sq. units
