Answer:
<h2>A. 2Pi</h2>Step-by-step explanation:
The given function is
Notice that the indepedent variable doesn't have any transformation, that means the period doesn't change. In other words, this function has the same period than its parent function which is .
Therefore, the answer is A.

<u>Answer:</u>
A. (x+5)
<u>Step-by-step explanation:</u>
We are given a quadratic expression which we will factorize to see which of the given options is a binomial factor of it.
Finding the factors of 15 such that when added, they give a result of 8.
Therefore, we can see that is that binomial factor that is present in the given options so option A. (x+5) is the correct answer.
