Nice try, actually, but not quite...
You are right to split it up into two pieces. You missed a couple of things.
The portion above the x-axis needs in the arguments and should be on [0,1].
The portion below the x-axis should be on [-1,0].
In every case, it should be "1-". I cannot tell where you managed any "1+". Further, if your limits are identical, you ARE going to get zero (0). Try negative on the bottom and positive on the top.
