Step-by-step explanation:
a) y = n – 0.26n
Given:
The function is:

To find:
The all the real and non-real roots of the given function.
Solution:
We have,

For roots,
,


Taking square root on both sides, we get


![[\because \sqrt{-1}=i]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7B-1%7D%3Di%5D)
The roots of the given function are -7i and 7i.
Therefore, the correct option is B.
Steps to solve:
k + 10 = 27
~Subtract 10 to both sides
k = 17
Best of Luck!
