If x = − 6 , which inequality is true? A. − 3 − 5 x < − 14 B. − 5 − 3 x > 10 C. 2 − x < − 3 D. 1 − 2 x > 13

Given the function f(x) = 3x + 1, evaluate f(a + 1). a. 3a + 1 b. a + 2 c. 3a + 4

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

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.
