Question
**Sketch the Region of Integration and Change the Order of Integration**

The given double integral is:

\[
\int_{0}^{4} \int_{0}^{\sqrt{x}} f(x, y) \, dy \, dx
\]

**Task:** Sketch the region of integration and change the order of integration.

### Explanation

The limits of integration for \( y \) are from \( 0 \) to \( \sqrt{x} \), and for \( x \) are from \( 0 \) to \( 4 \).

### Region of Integration

To visualize the region:
1. **x limits:** From 0 to 4.
2. **y limits:** From 0 to \(\sqrt{x}\).

This represents the area under the curve \( y = \sqrt{x} \) from \( x = 0 \) to \( x = 4 \).

### New Order of Integration

We need to express \( x \) as a function of \( y \) by solving \( y = \sqrt{x} \) for \( x \):
\[ x = y^2 \]

**New limits:**
- For \( x \): from \( y^2 \) to 4.
- For \( y \): from 0 to 2 (since \( \sqrt{4} = 2 \)).

This changes the order of the integral to:

\[
\int_{0}^{2} \int_{y^2}^{4} f(x, y) \, dx \, dy
\] 

### Summary

The integration order is switched from \(\int \int dydx\) to \(\int \int dxdy\), with the newly determined limits reflecting the same region of integration.
