Ok, so I know the function is increasing because which is positive Mr F wonders: Is it positive for all values of x ....?

also it is concave up because which is also positive Mr F says: What is the definition given for concave up in your class notes?

Please teach me how to solve for local extreme points Mr F says: What do your class notes tell you to do?

and inflection points, and for concavity, do I just answer concave up?
