Answer:
Option C
Explanation:
acc. to me the correct answer is option c.
simce we see that the dot is filled black for the line representing points x>1 so it should be greater than or equal to 1 case.
so you eliminate options a and b.
Left are option c and option d. In option d, the sign for both the function is for x>1 where case x<1 is not discussed.
So, from this I can deduce my answer to option C acc to my understanding.
