Okay, we have this piecewise defined function.
00:06
Okay, this piecewise defined function has three parts.
00:10
The first part is when x is less than or equals negative 1, okay? so let's start it with this part.
00:19
So negative 1 is here.
00:23
So when x is less than or equals negative 1, f of x is 3.
00:29
Okay, so this is 3.
00:32
Therefore, the graph will be a horizontal line that is parallel to, the x -axis and it ends at x equals minus at x equals negative 1.
00:48
The next part is between negative 1 to 2.
00:52
Okay, f of x is negative 2x plus 1.
00:57
So let's plug in two points, okay, find two other pairs so we can connecting them.
01:05
So when x is 0, f of 0 is minus 2 times 0 plus 1, which is 1, which is 1...
