The problem asks us to find the area of the region bounded by the curves $x = y^2 - 2$ and $x = y - 2$ on the interval $[-2, -1]$.

1. Problem Description

The problem asks us to find the area of the region bounded by the curves $x = y^2 - 2$ and $x = y - 2$ on the interval $[-2, -1]$.

2. Solution Steps

First, we need to find the intersection points of the two curves. To do this, we set the two equations equal to each other:

$y^2 - 2 = y - 2$

$y^2 - y = 0$

$y(y - 1) = 0$

So, $y = 0$ or $y = 1$.

However, we are only interested in the region where $y$ is between $-2$ and $-1$. Since neither $y=0$ nor $y=1$ lie in the interval $[-2,-1]$, the interval $[-2,-1]$ does not correspond to the bounded area between the curves from $y=0$ to $y=1$.

To find the area between the curves, we integrate the difference between the two functions with respect to $y$ over the given interval $[-2, -1]$. We need to determine which function is greater over this interval.

If $y = -1.5$, then $y^2 - 2 = (-1.5)^2 - 2 = 2.25 - 2 = 0.25$ and $y - 2 = -1.5 - 2 = -3.5$. Thus, $y^2 - 2 > y - 2$ on $[-2, -1]$ is not correct. Instead, $y - 2 > y^2 - 2$.

The area is given by the integral:

$A = \int_{-2}^{-1} [(y - 2) - (y^2 - 2)] dy$

$A = \int_{-2}^{-1} (y - y^2) dy$

$A = [\frac{1}{2}y^2 - \frac{1}{3}y^3]_{-2}^{-1}$

$A = [\frac{1}{2}(-1)^2 - \frac{1}{3}(-1)^3] - [\frac{1}{2}(-2)^2 - \frac{1}{3}(-2)^3]$

$A = [\frac{1}{2} + \frac{1}{3}] - [\frac{1}{2}(4) - \frac{1}{3}(-8)]$

$A = [\frac{3}{6} + \frac{2}{6}] - [2 + \frac{8}{3}]$

$A = \frac{5}{6} - [\frac{6}{3} + \frac{8}{3}]$

$A = \frac{5}{6} - \frac{14}{3}$

$A = \frac{5}{6} - \frac{28}{6}$

$A = -\frac{23}{6}$

Since the area cannot be negative, we take the absolute value:

$A = |\frac{-23}{6}| = \frac{23}{6} = 3.8333$

Something is wrong with the problem, since the range is wrong.

Let us suppose the range is from 0 to

1. $A = \int_0^1 (y - y^2) dy$

$A = [\frac{1}{2}y^2 - \frac{1}{3}y^3]_0^1$

$A = [\frac{1}{2} - \frac{1}{3}] - [0]$

$A = \frac{3}{6} - \frac{2}{6} = \frac{1}{6} \approx 0.16667$

If we instead consider the y interval to be between $-1$ and 0,

$A = \int_{-1}^0 (y-y^2)dy$

$A = [\frac{y^2}{2} - \frac{y^3}{3}]_{-1}^0 = 0 - [\frac{1}{2} - \frac{-1}{3}] = -[\frac{1}{2} + \frac{1}{3}] = -\frac{5}{6}$

So area $= \frac{5}{6} = 0.833333$.

It appears as though there's a typo, and the range should have been $[-1,0]$ instead of $[-2,-1]$.

Then the answer is close to D.

However, given the answers, the intended functions are $x=y^2$ and $x=y$, with the integral being from 0 to

1.

3. Final Answer

Since the interval is $[-2, -1]$, none of the answers seem to be correct. However, $\frac{23}{6} = 3.8333$, which is not one of the options.

Assuming the range is $[0, 1]$ and the functions are $x = y - 2$ and $x = y^2 - 2$, then $A = \frac{1}{6} \approx 0.16667$, and since none are near that, it is possible there may be a typo.

If the interval were $[-1.2,-0.8]$, the area would be closer to the answers.

Given the options provided, C. 0.15 sq. units is closest to the area if the curves were $x=y$ and $x=y^2$, and the range of y was from 0 to 1, yielding an answer of 1/6 = 0.
