Do you need help?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

ok, so Do you know what a derivative is?

OpenStudy (anonymous):

no, cant remember

OpenStudy (anonymous):

May I ask if you've taken calculus?

OpenStudy (anonymous):

Sure, no I haven't

OpenStudy (anonymous):

Thats probably why. okay so another way to find it without taking the derivative would be to plug the appropriate values into (-b/2a).

OpenStudy (anonymous):

Have you see that formula ----> -b/2a?

OpenStudy (anonymous):

Still with me?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

That took a while.

OpenStudy (anonymous):

i know.....

So, If I was to continue, would you leave for 2 hours this time?
