# Math Help - IS this the mgf of this function

1. ## IS this the mgf of this function

Hello there, I'm pretty new to mgf, so I was wondering if my solution to the mgf was correct. Thanks!

The pdf is

$
ae^{-a(t-2)}
$

and the possible range of values are from 2 to infinity

My solution is 1/(1-(t/a-2))

Thanks!

2. its correct....absolutely.....
