Answer 2

hahahha yes you understand!!

Answer 3

so i just did this problem and got 4.5 but im redoing it because it doesnt look right

Answer 4

k 1 sec

Answer 5

so the slope of that f ' (x) is the acceleration , which is a constant -1

Answer 6

from -3 to 0

Answer 7

Let over the inverval [-3,0]

f ' '(x) = -1
f '(x) = -1x
f (x) = -(1/2) x^2 + C

when x=0 y=7 so

f(x) = (-1/2) x^2 + 7

Answer 8

oh wait now i got 4.5

Answer 9

I got 2.5 is the minimum value for f at x=-3

Answer 10

see how i came up with those equations?

Answer 11

yess

Answer 12

thanks(:

Answer 13

i only have one more question if you could help me (:

Answer 14
