Yes were finally off of school but we still have to do our blogs... O.o
But thats not that bad :)

Average Speed:
An anvil falls off the roof onto Ryan's head. What is its average speed during the first two seconds if y=16t^2

0:y1=16(0)=0
2: y2= 16(2)^2=64

then you plug into the formula y2-y1/(0ver) x2-x1

after plugging in you would get the awnser of 32

Instantanesous speed:

lim f(x+h)-f(x)/(over)
h

find the speed at t=2

y=16t^2 lim 16(2+h)^2-16(2)^2

f(t)=16t^2

which whould give you 64

And im still having trouble with points of inflection and don't have notes and i know we don't have to comment this week whcih is awesome but i still asked a question.
