The given image shows a double integral transformation, where the limits of integration are switched, likely applying Fubini's Theorem. The integral on the left-hand side of the equation is:

$\int_0^2 \int_0^y f(x, y) \, dx \, dy$

This is equal to the integral on the right-hand side, but the order of integration is changed. To rewrite this integral correctly, we must adjust the bounds when switching the order of integration. The region described by the original bounds $0 \leq x \leq y$ and $0 \leq y \leq 2$ represents the triangular region in the $xy$-plane, bounded by $y = x$ and $y = 2$.

When we switch the order of integration, the bounds become:

$\int_0^2 \int_x^2 f(x, y) \, dy \, dx$

Thus, the full equation is:

$\int_0^2 \int_0^y f(x, y) \, dx \, dy = \int_0^2 \int_x^2 f(x, y) \, dy \, dx$

Would you like more detailed steps on how the bounds were transformed?

Here are 5 related questions to consider:

1. What conditions are needed to apply Fubini's Theorem?
2. How do you visualize the region of integration for different bounds?
3. What is the significance of changing the order of integration in practical applications?
4. How would the integral change if the limits were different, for example, if $f(x, y)$ had different boundary constraints?
5. Can this transformation be extended to triple integrals?

Tip: When changing the order of integration, always sketch the region of integration first to better understand how the limits change.
