What conclusions can be made using the following information (first and second derivatives): 1. f’(3) = 0 , f’’(3) = -2 2. f’(-2) = 0 , f’’(-2) = 2 3. f’(4) = 0 , f’’(4) = 0

Step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
