Based on census data, the population of Freedonia is modeled by the function P(t)= 310t^2+25474 people, where t represents the number of years after 1990. Use this function to determine how fast the population was increasing at the end of the year 1995.

Answer 1

Substitute t for 1995 in the function:

P(t) = 310*1995^2+25474

Answer 2

not quite.
t = 5
1995 is 5 years after 1990
