Ineed a math !me in my math homework. will mark as brainlist.

velocity is the slope (which can be calculated after finding the derivative)  →  given function f(x), velocity = f'(x).

acceleration is the slope of the velocity (which can be calculated after finding the derivative of the velocity)  →  given function f(x), acceleration is f''(x)

**************************************************************************************************

1a) A → B

f(x) =

f'(x) =

1b) B → C

f(x) =

f'(x) = = -5

1c) C → D

f(x) = 20

f'(x) = 0

Hope this helps!

answer is c
