The number of leaves on a maple tree increased exponentially since the beginning of spring. A graph of the function contains (3, 96) and (4, 384), where x is the
number of
weeks since spring began and y is the number of leaves. Which function models the
relationship between x and y?
F = 3(2)^x
G= 4(1.5)^x
H= 4(2)^x
J= 1.5(4)^x
