Can you also show the graph. please.

2).

The population of Eagle River is growing exponentially according to the model P(t) = 475(1.3)^t

people, where t is measured in years from the present date. Find the population in 3 years. (Round your answer to the nearest whole number.)

Answer 1

Given fre=y= SX-3 4+3 = 8% 9 +3 = x=f-ily) f-1(x) = 243 8 2 -11 - -3 5 12 f-1(x) -1 0.5 1 2 (511) $1,0-5) - all to us --5-2 2 E11,-1)

Population of Eagle einer PCH 475 0.33+ Population after 3 years = 2? t=3 PC3) = 475 C1-393 475 (2.197) - 104.575 = 1043 . Population in 3 years = 1043
