## Homework Statement

A discrete random variable Y has probability distribution given by

f(y;β) = (ky

^{2}β

^{(y+k)})/((β+3)

^{(y+2k)}(y+1)

^{1/2})

## Homework Equations

I know that for a pdf to be from generalised exponential family of distribution it can expressed as

f(y) = exp{(yθ-bθ)/a∅ +c(y,∅)}

## The Attempt at a Solution

From exp{log(f(y;β))} i got -----> exp[(y+k)log(βy)-(y+2k)log(β+3)+log ky - (1/2)log(y+1)]

Is this sufficient or does it require further work?
