Homework Statement
A function f( x ) had the following form : f ( x) = kx^-(k+1) where 1 < x < infinity
a) for what values of k is f a pdf ?
Homework Equations
See attachments (the theorem is included)
The Attempt at a Solution
started out by using the first equation in the attachment, for stuck with kx^-(k+1) = 0 and Got stuck there... well the only way k will satisfy the equation is that if it is equal to 0... but I'm not sure if that is the answer.
Tried using the 2nd equation, integration was long, and i encountered logs, K turned out to have a single value of 0.00693
--------------------------
ok i figured that my first attempt was right and that k is > = 0 . But i just want to confirm this, and i don't really feel like deleting my post after writing it out
