So fuctions mean if f(x)=x+2 then if you put in 3 for x then f(3)=3+2=5 so
if x=years after 2000 in 2020 then 2020-2000=20 so x=20 subsitute f(20)=9204e^0.022(20)
e could be: 1. common base of logarithms (memorised to 15 decmals) 2.718281828459045 2. a computer notation exg if you have 3e11 that means 3 times 10^11
if it is 1 9240 times (2.718281828459045^(0.022 times 20))=( simplify exponent first) 9240 times (2.718281828459045^0.44)=9204 times 1.5527072185113=14291.1 or rounded to 14291
if it is 2 9204 times 10^(0.022 times 20)=9204 times 10^(0.44)=9204 times 254.491 rounded to 254
so the answer dependes on what e represents,
if e is: 1. common base of logarithms (memorised to 15 decmals) 2.718281828459045, then answer is 14291
2. a computer notation exg if you have 3e11 that means 3 times 10^11 =254
