Question

The figure shows the graphs of f, f ', and f ''. Identify each curve.

Answer 1

as derivatives go up; curves get less curvy

Answer 2

f is curvyest
f' less curvy then f
f'' = least curvy of the all

the porridge is too hot .. this is too cold, and this one smells like bear dung

Answer 3

I tried C for f, B for f', and C for f", but it was wrong :/

Answer 4

well, you cant use C twice

Answer 5

sorry i meant a for f"

Answer 6

yeah, these dont seem to be nice and polynomial like ...

Answer 7

each derivative tells you about the slope at the point of the one before it

Answer 8

a would indicate a negative slope on the left of one of the others; and they aint got no negative slope there so id assume a is the f

Answer 9

and it changes to negative about the time b goes under the x; so id say b is f'

Answer 10

that leaves c for f''

Answer 11

try a b c

Answer 12

Oh i see what how you look at the slopes now. That was right. Thanks!

Answer 13

trying to work of memory aids will work most of the time and then mess you up for the other :)
