Given the piecewise function 2x and x plus 1, where the first piece is defined if x is less than 1, and for the second piece, x is greater than or equal to 1.
00:11
We want to graph, and then we want to determine what is the limit as x approaches 1 of this function.
00:17
So let's start by graphing it.
00:20
Let's start with the first piece.
00:21
If x is 1, then the output is 2, but it's not including that, so it's open circle, and then to the left, like 2 times an input.
00:32
Of negative 2 is negative 4.
00:43
If x is 1, the output is 2.
00:46
There we go.
00:48
And the slope is 2...
