The height of a tree in feet over x years is modeled by the function f(x).
Evgesh-ka [11]

If e-the initial hight of the tree, and the function imply some brackets like

f(x)=30/(1+29e-0.5x) then

for every

0.5x > 29e + 1

the rate of growth is negative, the maximum growth per unit of time would be 30ft

If

x \geqslant 1

then

29e <  - 0.5

so the tree couldn't be 2ft tall initially

if the brackets are something like

f(x)=30:(1+29e)-0.5x then the results may differ
