<em>Note: Since you missed to mention the the expression of the function </em><em> . After a little research, I was able to find the complete question. So, I am assuming the expression as </em><em> and will solve the question based on this assumption expression of </em><em>, which anyways would solve your query.</em>
Answer:
As
Therefore, is a root of the polynomial <em> </em>
As
Therefore, is not a root of the polynomial <em> </em>
Step-by-step explanation:
As we know that for any polynomial let say<em> </em><em>, </em> is the root of the polynomial if .
In order to find which of the given values will be a root of the polynomial, <em>, </em>we must have to evaluate <em> </em><em> </em>for each of these values to determine if the output of the function gets zero.
So,
Solving for
<em> </em>
Thus,
Therefore, is a root of the polynomial <em> </em><em>.</em>
Now, solving for
<em> </em>
Thus,
Therefore, is not a root of the polynomial <em> </em><em>.</em>
