Problem: Find the area of the region bounded by the graphs as shown in the picture, given that the 4a=2.
Equation of line:
$y + 2 = \dfrac{4 + 2}{8.5 - 2.5}(x - 2.5)$
$x = y + 4.5$ ← $x_R$
Equation of parabola:
$y^2 = 2(x - 0.5)$
$x = \frac{1}{2}y^2 + 1$ ← $x_L$
$\displaystyle A = \int_{y_1}^{y_2} (x_R - x_L) \, dy$
$\displaystyle A = \int_{-2}^{4} \left[ (y + 4.5) - \left( \frac{1}{2}y^2 + 1\right) \right] \, dy$
Thanks men! Love the approach
