Answer:

C is correct

Step-by-step explanation:

Given: [tex]f(x)=4-7x^5[/tex]

This is polynomial equation with degree 5 and two term. Write polynomial in standard form from highest degree to lowest degree.

Degree: Highest power of the polynomial.

Coefficient of leading term: The number front of variable.

  • [tex]f(x)=-7x^5+4[/tex]

Degree = 5

Leading coefficient = -7

f(x) is a polynomial function. The degree is 5 and the leading coefficient is -7
