# What is and amplification factor in pseudo-random generators?

I can’t seem to find an answer to this. For instance, I have this question:

Show that, if $$P=NP$$, there aren’t any pseudo-random generators (even with amplification factor $$n+1$$).

My gut tells me this is because, in a world where $$P=NP$$, pretty much any process can be efficiently inverted so there aren’t one-way functions (which pseudo-random generators rely on).
