Question

A plant is already 15 centimeters tall, and it will grow one centimeter every month. Let H be the plant's height (in centimeters) after M months. Write an equation relating H to M. Then graph your equation using the axes

Answer 1

H = 15 + M

Explanation:

The plant starts out at 15 cm tall, therefore the y intercept is (0,15) and there is an x intercept but it isn't valid in this case as a plant cannot grow backwards (I assume). The domain would be (0,infinity) and the range would be (15,infinity).
