Find the roots of the polynomial function f(x) = x^3 + 2x^2 + x

:24% of students in a class are girls. if there are less than 30 students in this class, how many students are there? how many girls are there?

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. 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.
