For this problem, we are asked to determine if the following statement is true or false, that the sealing function of negative x equals the negative of the floor function of x.
00:10
Now, there are a few ways that we can go about doing this, but let's first start by considering, for example, a couple of values.
00:16
So let's say we take the value negative 2 .4.
00:20
The sealing function of negative 2 .4, that is the greatest or the least integer greater than negative 2 .4, would be the ceiling function of negative 2 .4, would be the be negative 2.
00:32
Meanwhile, if we imagine taking 2 .4, we can see that the floor of 2 .4 would give us a value of 2.
00:41
Which then means that the negative value of the floor of 2 .4, ah, bad habit.
00:50
Okay, there we go...
