Answer:


A= -(3)/(2)

area between curve and the x-axis, within the intervals
x=[-\infty,0)

Explanation:

Given function is:


f(x) = (x)/((x-1)^3)

to find its area between the intervals
x=[-\infty,0), we'll need to integrate it.


A = \displaystyle{\int^0_(-\infty) {(x)/((x-1)^3) \, dx}


A = \left|- (3)/(2 \left(x - 1\right)^(2))\right|^0_(-\infty)


A = \left(- (3)/(2 \left(0 - 1\right)^(2))\right)-\left(- (3)/(2 \left(-\infty - 1\right)^(2))\right)


A= \left(- (3)/(2)\right)-0


A= -(3)/(2)\,\text{unit}^2
