A T-shirt manufacturer is planning to expand its workforce. It estimates that the number of T-shirts produced by hiring x new workers is given by T(x) = - 0.25x"+ 8x , Os Xs 24. When is the rate of change of T-shirt production increasing and when is it decreasing? What is the point of diminishing returns and the maximum rate of change for T-shirt production? Graph T and T' on the same coordinate system. The rate of change of T-shirt production is increasing on (Type your answer in interval notation.) The rate of change of T-shirt production is decreasing on (Type your answer in interval notation.) The point of diminishing returns is x = workers. The maximum rate of change for T-shirt production is |T-shirts per worker. Graph T and T' on the same coordinate system. O A. O B. O C. O D.
