3 hours into my three problem homework just now finding out you plug in 0 for h is all I needed for the past couple hours. I had to teach myself how to do this my teacher only taught us aroc.

Thank you! I was so lost on the evaluating part and didn’t realize I have to plug in 0. A life saver !!!

Thanks very much I had no idea how to put a root with a variable plus a constant into the formal definition of a derivative.

At the 3:31 mark. When adding your bottom 9+3, why is it 6 and not 12?

Great video you really helped with my hw! But question, this might be a bit tedious but when you got to the last step at lim h->0 1/sqrt(9-h)+3 ... shouldn’t that sign have been positive inside the square root

if the m=0 do i still have to write it at the final anwer? like y=0x+15?

What is the function isnt f(x). My problem is y= sqrt 1-x. (0, 1). Is it the same with y?

WOAHH! f(xo) = y??? THANKS! That's why I was always wrong 😅
