True or False: the function f(x)=3x^3+x^2+2x rises as x grows very small. I don't really even understand what is being asked here.

OpenStudy (nuttyliaczar):

What happens to f(x) as x gets smaller?

OpenStudy (nuttyliaczar):

You're basically just doing a limit as x approaches zero

OpenStudy (anonymous):

Could you walk me through the problem?

OpenStudy (anonymous):

I know that as x gets closer to 0, so does y

OpenStudy (nuttyliaczar):

Yep that's all that was being asked

OpenStudy (nuttyliaczar):

So f(x) decreases as x decreases

OpenStudy (anonymous):

so it would be false

OpenStudy (nuttyliaczar):

Yes
