Ma'am I have a dout.?
When u draw a parallel line for x- axis why didnt you not considered the parallel line on 4 th quadrant also .
I this question we see that at 4 the quadrant it touches 2 points .

[raguraamdhandapani]

In the 4 the quadrant the graph shouldn't touch the X axis mam

[andrewjustin]

One thing is to be noted that x axis check is meant to be done in all quadrants, which makes this many to one function.

[ramchandraraya]

Mam but a parallel line can be drawn below rhe axis .If it is done then we find two points .So this is not one - one .I think u should respond our comment otherwise delete such videos because it creates confusion.
