Consider f(y) = -8y(139) and use the Second Derivative Test to address the following prompts. Determine the value and location of any local minimum of f. Enter the solution in (y, f(y) ) form. If multiple solutions exist, use a comma-separated list to enter the solutions. Of has a local minimum at: Of has no local minimum. Determine the value and location of any local maximum of f. Enter the solution in (y, f(y) ) form. If multiple solutions exist, use a comma-separated list to enter the solutions. Of has a local maximum at: Of has no local maximum
