Answer 1

The polynomial \(-5x^3 - 4x + 1\) is a **cubic trinomial**.

Here's the breakdown:
- **Cubic**: The highest degree of the polynomial is 3 (the term \(-5x^3\)).
- **Trinomial**: It has three terms (\(-5x^3\), \(-4x\), and \(1\)).

Therefore, the correct description is: **cubic trinomial**.
