Question

Eileen has a greenhouse and is growing orchids. The table shows the average number of orchids that bloomed over a period of four months: Month 1 2 3 4 Orchids 11 12.4 13.8 15.2 Did the number of orchids increase linearly or exponentially?

Answer 1

9514 1404 393

Answer:

linearly

Explanation:

The month-to-month difference in the numbers of orchids is 1.4, so the increase is linear.

_____

If the numbers of orchids had a constant ratio, and/or if the differences had a constant ratio (not 1), then the relation would be exponential.
