What is the relationship between the zeros of a polynomial and its factors?

• Zeros are unrelated to factors

• Zeros determine the factors

• Factors are the sum of zeros

• Factors are the product of zeros

What is the significance of the constant 'A' in a polynomial function?

• It changes the degree of the polynomial

• It affects the zeros of the function

• It can be any constant and does not affect the zeros

• It must always be zero

How do complex zeros appear in polynomial functions?

• As single numbers

• In conjugate pairs

• As real numbers

• As imaginary numbers only
