Which could be the entire interval over which the function, f(x), is negative?
a) (–8, –2)
b) (–8, 0)
c) (–∞, –6)
d) (–∞, –4)

Ihonestly don’t understand this at all

20 solve 2(4 x + 3) < 5 x + 21. a) { x | x < 9} b) { x | x > -5} c) { x | x > -9} d) { x | x < 5}

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.
