1. are the triangles similar and if so why? what is the value of x? show your work.

Over which interval is the graph of f(x) = x2 + 5x + 6 increasing?

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.
