After assigning her variables and setting up her objective function and constraint equations, Estelle uses the first derivative test and gets a negative value for her variable "x". What should Estelle conclude? a) The answer should not be negative, and she should reject her answer and check her work b) Her answer is probably fine, and she should check her variable assignment and set-up to c) The problem must have no solution and she should state this as her answer for any mistakes see what the interpretation is before rejecting None of these choices (write a brief statement explaining why in the space below) d)
