x => 2
x cannot be below 2.
The sqrt of something negative is always imaginary.

Those two down there got me.
Forgot about the x next to it lol.
A negative time a negative is positive so values below 0 will work.

x only can't be between 0 and 2, because those values make x*(x-2) negative (when you think negative products, think different signs) and square roots can't be negative.
