1. Rosetta is growing a bamboo plant in her apartment. The height of the plant is a linear-to-Iinear function of time. Thirty days ago, the plant was 14 cm high. Today, the plant is 18 cm high. The plant always increases in height, and will approach (but never exceed) a height of 32 cm. (a) Find a function representing the height of the plant as a function of time. (spams) (b) Rosetta also has a fast-growing cactus. Today, its height is 9 cm. The cactus grows at a constant rate of 1 cm per day. When will the cactus and the bamboo plant be the same height?
