The population of city A changes according to the exponential function
A(t) = 2.9 (2)
0.11 t (millions)
and the population of city
B changes according to the exponential function
B(t) = 1.7 (2)
0.17 t (millions)
where t = 0 correspond to 2009.
a) Which city had larger population in 2009?
b) When will the sizes of the populations of the two cities be equal?
