@artofspeed Please don't just give the answer. Explain it to them. Guide them so they can get the answer themselves. 
Thanks.

The numbers that fall in $x$ can be 5, 5.0000000001 or something more as long as it is greater than or equal to 5.

parthkohli · Answer

In interval notation, you can represent this easily. The starting value is 5 including 5, and the ending value is infinity but not including infinity.$$[5,+\infty) $$Do you get it?

Thank you, I understand that...but my book says that the answer is (-x, 5]

myininaya · Answer

@ParthKohli It says x<5 or x=5

Not the following:
x>5 or x=5
