Ms. Sue can you answer this please

Damon had answer, but i just want to see if you'll explain it differently...
The population of a town P(t)is modelled by the function P(t)=6t^2+110t+3000, where t is time in years. Note t=0 represents the years 2000. When will the population reach 6000?
Damon is the expert. I have no idea how to answer this question. I never learned about functions.
Damon's expertise it too expert for my knowledge and math level
thank you though Ms Sue.
just plug it in. 6t^2+110t+3000=6000, thus 6t^2+110t-3000=0 and we factor but first we divide by 2. Thus we get the equation 2(3t+100)(t-15)=0. FYI if you did not learn what just happened please study your algebra book. Anyway, x= -100/3 or 15, but it cannot be negative so t=15. Thus, 2000+15 = 2015
