**Polynomial Analysis**

In this exercise, we are tasked with analyzing the polynomial function: 

\[ p(x) = 14 + 5x^4 - 7x^5 \]

### Tasks:

**(A) The leading term of the polynomial**

The leading term of a polynomial is the term with the highest power of \( x \). For the polynomial \( p(x) = 14 + 5x^4 - 7x^5 \), the leading term is:

\[ -7x^5 \]

**(B) The limit of \( p(x) \) as \( x \) approaches \(\infty\)**

The limit as \( x \) approaches infinity determines the behavior of the polynomial for very large values of \( x \). The leading term, \( -7x^5 \), dominates the behavior. As \( x \rightarrow \infty \), \( -7x^5 \rightarrow -\infty \).

**(C) The limit of \( p(x) \) as \( x \) approaches \(-\infty\)**

Similarly, for very large negative values of \( x \), the leading term also dominates the behavior of the polynomial. As \( x \rightarrow -\infty \), \( (-7x^5) \) also approaches \(-\infty\).

### Conclusion:
- The polynomial's leading term is \( -7x^5 \).
- As \( x \) approaches \(\infty\), \( p(x) \) approaches \(-\infty\).
- As \( x \) approaches \(-\infty\), \( p(x) \) also approaches \(-\infty\).
