If synthetic division reveals a zero, why should we try that value again as a possible solution? - polynomial functions can have imaginary zeros, so if it is an imaginary zero, it could also be a real zero. - polynomial functions can have repeated zeros, so the fact that a number is a zero doesn't preclude it being a zero again. - polynomial functions can have real zeros, so the fact that a number is a real zero means it could also be an imaginary zero. - polynomial functions can have imaginary zeros, so if it is a zero, it could also be an imaginary zero. - polynomial functions can have rational zeros, so trying a value again can find irrational zeros.

The correct option is:

Polynomial functions can have repeated zeros, so the fact that a number is a zero doesn't preclude it being a zero again.

Step-by-step explanation:

As we know that if we get a zero of a polynomial than that particular zero could also be a zero of multiplicity greater than one or in short we can say that it is a repeated zero of the polynomial.

Hence, in order to check that it is a repeated zero we factorize the polynomial and see that it is a zero of the other factor or not if it is a zero of the other factor then we will say that the zero is a repeated zero of the polynomial.

step-by-step explanation:

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
