Let f be a function defined for all real numbers. Also, let f', the derivative of f, be defined as f'(x)=((x-2)^3))/x. Options are (-Infinite, 0) and (2, infinite) (-Infinite,...

Round to the nearest three decimal places. I'm not sure if i should take the derivative and then solve for 0. Using critical values. I'm very confused and my notes are no help.

1. Chips Ahoy wants to perform a study to determine the number of chocolate chips in their cookies. To that end, they collected a sample of 40 cookies. The mean of this sample is 23.95 chocolate chips...
