Exponential growth world problem (tree)

[Guest]

The height of a certain species of tree can be modelled by the function H = 10 /(8 + 50e^-0.4t), where H is the height of the tree in metres and t is the age of the tree in years since it was planted. The height of the tree when planted is approximately what?

The height of the tree when planted is approximately what?

what is so difficult about this question? ... plug in 0 for t and determine H.
