It gets rid of the line where x is negitive. for all the positive values of x it equals one.

Sure, it's equal to minus one, but it also sets a domain that must be larger than zero.

They are in every of this equations, to "hide" parts of them.
In this case for every negativ number the square root becomes imagniary and is therefore not in the diagramm. Hide some parts of the functions and combine them to get things like this.

oh, and of course because the square root is multplied with the rest the whole function becomes imagniary for negative numbers.
