I don't understand this question at all

It is estimated that the annual advertising revenue received by a certain newspaper will be

R(x) = 0.5x2 + 3x + 160 
 
thousand dollars when its circulation is x thousand. The circulation of the paper is currently 10,000 and is increasing at a rate of 3,000 per year. At what rate will the annual advertising revenue be increasing with respect to time 2 years from now?

This question is still not correct.  I had stated last time that your function is not with respect to time to begin with.
