Question:

A gardener planted a new variety of ornamental grass and kept a record of its height over the first two weeks of growth.

a. How much does the grass grow each day?
b. Write an explicit formula that gives the height of the grass after n days.
c. How long will it take for the grass to be 28 cm tall?
Heather Ackroyd and Dan Harvey print photographs on grass, such as this one, Sunbathers 2000. They position a photographic negative over growing grass, and the chlorophyll reacts to give a temporary image in shades of green and yellow. They use genetically modified grass to make their images last longer.
