The area of a rectangular garden in square feet can be represented by <? - 10x + 21. The length is 2 - 7 feet. You have been hired to fertilize the garden. Recall that the area of the garden is 22 - 10x + 21. If 3 = 20 and the fertilizer costs $0.27 per square foot, how much will it cost to fertilize
the garden?

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
