Question

What is a zero of a polynomial function?

A. A coefficient of the polynomial that is equal to zero

B. The coefficient of the leading term of the polynomial

C. The value of the polynomial when zero is substituted for the variable

D. A value of the variable that makes the polynomial equal to zero

Answer 1

a

Answer 2

d

Answer 3

D. This is a definition so remember it. The zero of a polynomial (or a function) is the value of \(x\) such that \(a_nx^n+a_{n-1}x^{n-1}+\ldots+a_{2}x^2+a_1x+a_0=0\)

Answer 4

For a function, it is the value of \(x\) such that \(f(x)=0\).
