Question: Let f(t) be the function from Exercise 39 that gives the height (inches) of a plant at time t (weeks). (a) When is the plant

Let f(t) be the function from Exercise 39 that gives the height (inches) of a plant at time t (weeks).

(a) When is the plant 11 inches tall?

(b) When is the plant growing at the rate of 1 inch per week?

(c) What is the fastest rate of growth of the plant, and when does this occur?


Exercise 39

The height of a certain plant, in inches, after t weeks isf(t) = 1 .05 + e-0.4t*

 The graph of f (t) resembles the graph in Fig. 3. Calculate the rate of growth of the plant after 7 weeks.

f(t) = 1 .05 + e-0.4t*
