Let L = f(h) be the amount of water in liters) a species of tree needs per week when it is h meters tall. A particular tree of this species in the PSU arboretum is h meters tall, and so it requires (h) liters of water per day, and we define + f(h). Assume that is invertible. (a) What is the practical meaning of the expression f(+3)?
(b) What is the practical meaning of the statement f(h+ 1) = ++3?
(c) What is the practical meaning of f(h/2)?
(d) What is the practical meaning of sih - 5) - 3/2?
(e) What is the practical meaning of -(0+2)? We now let o(t) be the height of another tree of this species t years after 2000. For these parts, give your answer in terms of the functions.9.-, and/or g!.
(f) How much water did this tree need in 2013?
(g) How tall is a tree that needs 15 L per week?
(h) In what your did this tree need 40 L per week? (1) When was this tree 9 m tall?
