This question that gives me a piecewise function, and it wants me to find f of negative a half, f of 0 .1, and f of a half.
00:25
So the function they give me, negative 2, if i'm between negative a half and negative 1 .5, negative 1 if between negative 0 .5 and negative 1 half, 0 if between negative a half and a half, and 1 if between.
01:13
So let's look.
01:16
So let's look at the first one.
01:18
We want to know when x is negative a half.
01:23
So that includes negative a half.
01:25
So if i look at this one right here, this doesn't include negative a half.
01:31
It's everything less than negative a half.
01:35
So it wouldn't be that one.
01:37
You would have to look at this one.
01:39
This one includes negative a half...
