    Hi everyone,

    im not sure if im missing anything here, but the question is asking for us to comment on the behaviour of the pdf as beta increases
    but we are told x>=\beta
    so any increase to the denominator would surely be more than any increase to the numberator (beta)
    so i would hva esaid that the pdf got smaller.
    why is it the case that the pdf increases?

    thanks

    You need to consider beta alone, x is a constant which we assume is greater than beta, so if we increase beta the pdf increases.

    This question was tricky!
