4.it remains constant.	Choose the correct choice
A) 2
B) 18
C) 1
D) 77
E) 33
Typical question. Taking k =5 and we draw the graph,   If x increases y decreases but when x equal to k, y value becomes infinite. But when x is greater than k, y value slowly reaches to 1. So it decrease from infinite to 1.   Answer:18
