Question 999910
You're correct on the first derivative test. 
.
.
On the second derivative test, you can't use {{{x=0}} as a test point because the function and the derivatives are not defined there. Choose any other point and since you have a jump at {{{x=0}}} use a point before and after. 
{{{x=-1/2}}} and {{{x=1}}} will work.
Then keep using the same reasoning that you've used and it will serve you well.
