(C) The curve is given by $x = 2 - y - y^2$. The $Y$-axis is the line $x = 0$. To find the points of intersection with the $Y$-axis,set $x = 0$: $2 - y - y^2 = 0 \implies y^2 + y - 2 = 0$. Factoring the quadratic: $(y + 2)(y - 1) = 0$,so $y = -2$ and $y = 1$. The area $A$ is given by the integral $\int_{-2}^{1} |x| dy = \int_{-2}^{1} (2 - y - y^2) dy$. Evaluating the integral: $A = [2y - \frac{y^2}{2} - \frac{y^3}{3}]_{-2}^{1}$. At $y = 1$: $2(1) - \frac{1}{2} - \frac{1}{3} = 2 - \frac{5}{6} = \frac{7}{6}$. At $y = -2$: $2(-2) - \frac{(-2)^2}{2} - \frac{(-2)^3}{3} = -4 - 2 + \frac{8}{3} = -6 + \frac{8}{3} = -\frac{10}{3}$. $A = \frac{7}{6} - (-\frac{10}{3}) = \frac{7}{6} + \frac{20}{6} = \frac{27}{6} = \frac{9}{2}$ sq. units.
