A). The function is increasing where its derivative is positive.
Its derivative is positive from 2 to 6, and from 8 to 10.
B). The function is decreasing where its derivative is negative.
Its derivative is negative from 0 to 2, and from 6 to 8.
C). The function has a relative minimum where its derivative is zero
and changing from negative to positive.
Its derivative is zero and changing from negative to positive at 2 and 8.
D). The function has a relative maximum where its derivative is zero
and changing from positive to negative.
Its derivative is zero and changing from positive to negative at 6 and 10.
E). The function is concave up between consecutive relative maxima.
The interval between consecutive relative maxima is 6 < x < 10 .
F). The function is concave down between consecutive relative minima.
The interval between consecutive relative minima is 2< x < 8 .
G). The function has points of inflection where its second derivative is
zero, that is, where its first derivative is a relative minimum or a relative
maximum.
Its first derivative is a relative minimum or maximum at x = 0, 4, 7, and 9 .
H). Good luck on the sketch !
Answer:
The 20-day old worm is 
inches more longer than the 10-day old worm.
Step-by-step explanation:
Jack is growing Red wiggler worms to help make compost. He measured the lengths of two young worms. The 10- day old worm is 
inch long. The 20-day old worm is 
inches long.
Therefore, the 10-day old worm is i.e inches long.
And the 20-day old worm is i.e. 
inches long
Therefore, the 20-day old worm is 
inches more longer than the 10-day old worm. (Answer)
Answer:
4
Step-by-step explanation:
Slope= y2-y1/x2-x1
(1,5) is placed as (x1,y1) and (-1,-3) is placed as (x2,y2)
Plug it in
-3-5/-1-1
Simplify
-8/-2 = 4
Slope=4
