Hi i need help on solving this question.
The population, P(t) of a city is modelled by the function P(t)=14t^2 + 650t + 32000
When will the population reach 50000?
I want to know what we are looking for, and how to get to that answer. Tnx

Well t is the time I suppose. Since the question is asking for "when" then we are solving for t. So we want to find out when the population reaches 50000 and P(t) is the population at a certain time. Then substitute 50000 into P(t). Then solve for t. If you need further help or your answer checked, I'll be happy to help.
