Let's solve the problem step by step:
### **Step 1: Set up the equations**
We have two curves:
- \( x = 2y \)
- \( x = y^2 - 3 \)
### **Step 2: Find intersection points**
Set the equations equal to each other to find the y-values where they intersect:
\[
2y = y^2 - 3
\]
\[
y^2 - 2y - 3 = 0
\]
This is a quadratic equation. Factor:
\[
(y - 3)(y + 1) = 0
\]
So,
\[
y = 3 \quad \text{and} \quad y = -1
\]
### **Step 3: Set up the area integral**
The area between the curves from \( y = -1 \) to \( y = 3 \) is:
\[
\text{Area} = \int_{-1}^{3} [\text{Right Curve} - \text{Left Curve}]\, dy
\]
Here, the right curve is \( x = 2y \), and the left curve is \( x = y^2 - 3 \):
\[
\text{Area} = \int_{-1}^{3} [2y - (y^2 - 3)]\, dy
\]
\[
= \int_{-1}^{3} [2y - y^2 + 3]\, dy
\]
### **Step 4: Integrate**
Integrate term by term:
\[
\int_{-1}^{3} (2y - y^2 + 3)\, dy = \left[ y^2 - \frac{y^3}{3} + 3y \right]_{-1}^{3}
\]
### **Step 5: Evaluate at bounds**
First, at \( y = 3 \):
\[
(3)^2 - \frac{(3)^3}{3} + 3(3) = 9 - \frac{27}{3} + 9 = 9 - 9 + 9 = 9
\]
Now, at \( y = -1 \):
\[
(-1)^2 - \frac{(-1)^3}{3} + 3(-1) = 1 - \left(-\frac{1}{3}\right) - 3 = 1 + \frac{1}{3} - 3 = -2 + \frac{1}{3} = -\frac{5}{3}
\]
### **Step 6: Subtract lower from upper**
\[
\text{Area} = 9 - \left(-\frac{5}{3}\right) = 9 + \frac{5}{3} = \frac{27}{3} + \frac{5}{3} = \frac{32}{3}
\]
---
## **Final Answer**
\[
\boxed{\frac{32}{3}}
\]
So, the area of the shaded region is **\(\frac{32}{3}\)**.
