### Question: Identifying Non-Possible Zeros of a Polynomial Function

**Problem Statement:**
Which of the following is **not** a possible zero of \( f(x) = 2x^5 - 5x^3 + 14 \)?

**Options:**
- \( \boxed{\frac{3}{5}} \)
- \( 7 \)
- \( 3 \)
- \( \frac{5}{2} \)

**Explanation of Choices:**
You need to determine which of these numbers cannot be a solution to the polynomial equation \( f(x) = 0 \). Each option represents a possible candidate for the roots of the function \( f(x) \).

Understanding this is crucial in mastering the concept of polynomial functions and their roots. Identifying the correct answer involves either analytical methods or a quick examination of whether each candidate satisfies the polynomial equation.

**Note:**
To determine if a number \( a \) is a zero of the polynomial function \( f(x) \), substitute \( a \) into the function \( f(x) \). If \( f(a) = 0 \), then \( a \) is a zero of the function.

This question is designed to test your knowledge of polynomial root-finding and zero identification, fundamental in algebra and precalculus studies.
