Question

I need help understanding the solution. Please, help me.
My question is: Why F(u) =1 when u >2?

Answer 1

for u <-1 and \(-1\leq u\leq 2\), I got those parts.

Answer 2

Seems to me that "Why F(u) =1 when u >2?" is simply the definition of the last part of a multipart (piecewise) function, and that it's to be accepted as fact (given), rather than be explained.

Answer 3

No, there is an explanation there, from "Also......" but I don't get it :(
