Here, we're given a function and we want to find a formula for this function.
00:05
Well, it's going to be a piecewise function.
00:07
So let's just start off with f of x equals.
00:11
And we have three different parts.
00:13
We have what happens if x is zero up until and not including three.
00:20
And then what happens if x is between three and five? oops, sorry, not including that three.
00:28
Or what is what happens if x is between six? and nine, including nine.
00:35
Notice there is no value between five and six, and that's okay.
00:38
So we just have to figure out what each of these equations are.

Now, i won't have time to do all of them, but i will do one...
