Answer:
Step-by-step explanation:
Assuming one root of a polynomial function is
Then the other root is
The reason is that , complex roots of polynomial functions occur in pairs.
One complex root is the conjugate of the other.
This means that, if
is a root, then
is also a root.
The information about the rational numbers and integers shows that the correct option is C.
<h3>How to explain the information?</h3>It should be noted that rational numbers are numbers where we can write as a fraction of two integers. Any rational number is in the form a/b where a,b are integers and b is nonzero.
Terminating decimals can be written as a rational number. Something like 3.1 is equivalent to 31/10.
Of the four answer choices, only choice C is correct.
Choice A has the value '3' as a rational number, but it doesn't have it in the set of integers as well. So that's why choice A is incorrect.
Choice B has -3.4 in the set of integers, which is not correct. Integers do not have any decimal portion. The same applies to choice D also. We can rule choices B and D out.
Therefore, the correct option is C.
