Answer:
C. k = -3
Step-by-step explanation:
First of all please try and understand math, cheating will never get you anywhere :)
So we can deduce that the value k is -3 for the following reasons:
If k is greater than 1, it will become narrower
If k is negative, it will shift right
Therefore we can conclude that k = -3
(I might be wrong but we will see)
