PIECEWISE Functions: Use CASES with INEQUALITIES in MATH

[00:00:00]And with a peace-wise function like this,  you've got cases. And for the given input -1/3, in this case, you've got to decide which  case is it in. Inequalities sometimes confuse people. You got to be careful! It's the  second case: -1/3 is greater than -1. On a number line, - 1/3 is to the right of -1 is therefore  greater than -1. So it fits the second case.

[00:00:30]So you use the second formula.  You replace x with the input -1/3 and you get -1 + 1 is zero.
