Question
**Title: Decomposing Integrals into Odd and Even Functions**

**Objective:**
Learn to write the integral of a polynomial function as the sum of the integrals of an odd function and an even function.

**Problem:**
Evaluate the following integral:
\[
\int_{-3}^{3} (x^3 + 7x^2 - 5x - 8) \, dx
\]

**Approach:**
We aim to express this integral as the sum of two separate integrals: one for an odd function and one for an even function.

**Options:**
1. \(\int_{-3}^{3} (x^3 - 8) \, dx + \int_{-3}^{3} (7x^2 - 5x) \, dx\)
2. \(\int_{-3}^{3} (x^3 - 5x) \, dx + \int_{-3}^{3} (7x^2 - 8) \, dx\)  *(Selected Option)*
3. \(\int_{-3}^{3} (x^3 - 5x - 8) \, dx + \int_{-3}^{3} 7x^2 \, dx\)
4. \(\int_{-3}^{3} x^3 \, dx + \int_{-3}^{3} (7x^2 - 5x - 8) \, dx\)
5. \(\int_{-3}^{3} (x^3 + 7x^2) \, dx + \int_{-3}^{3} (-5x - 8) \, dx\)  *(Correct Answer)*

**Solution:**
Using the selected correct option:
\[
\int_{-3}^{3} (x^3 + 7x^2) \, dx + \int_{-3}^{3} (-5x - 8) \, dx
\]

**Evaluation:**
By symmetry properties of odd and even functions, simplify the integral:

\[
\boxed{-90}
\]

This approach breaks the integral into components, utilizing the properties of odd and even functions for efficient evaluation.
