Is the function f(x) = 4 - 7x^5 a polynomial function? If so, state its degree and leading coefficient.

A. f(x) is not a polynomial function.
B. f(x) is a polynomial function. The degree is 7 and the leading coefficient is 4.
C. f(x) is a polynomial function. The degree is 5 and the leading coefficient is negative 7.
D. f(x) is a polynomial function. The degree is 5 and the leading coefficient is 4.

Answer 1

f(x) = -7x^5 + 4 is a polynomial function with degree 5 and leading coefficient -7.
Letter C

Answer 2

C is correct

Explanation:

Given:
`f(x)=4-7x^5`

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.

• 
  `f(x)=-7x^5+4`

Degree = 5

Leading coefficient = -7

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