The function \( f(x) = 4 - 7x^5 \) is indeed a polynomial function.
To identify its degree and leading coefficient:
- The highest power of \( x \) in the function is 5, so the degree of the polynomial is 5.
- The leading coefficient is the coefficient of the term with the highest degree, which in this case is -7.
Therefore, the correct response is:
**f(x) is a polynomial function. The degree is 5 and the leading coefficient is negative 7.**
