Which of the following statements must be true about the polynomial function f(x)? if 1+ the sqrt of 13 is a root of f(x), then -1- the sqrt of 13 is also a root of f(x). if 1 + 13i is a root of f(x), then 1 – 13i is also a root of f(x). if 13 is a root of f(x), then –13 is also a root of f(x). if –13 + i is a root of f(x), then 13 + i is also a root of f(x).

the correct answer is b on edge

The correct answer is: if is a root of , then is also a root of .

In fact, every polynomial has real and/or complex solutions. If all solutions are real, we're good. But if not all of them are real, then the complex ones come in couple of conjugate solutions. Since and are conjugate complex numbers, if one of them is a solution, the other must be as well.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
