The cost C (in dollars) of producing x units of a product is C = 60x +
Question:
The cost C (in dollars) of producing x units of a product is C = 60x + 1350. For one week, management determined that the number of units produced x at the end of t hours can be modeled by x = −1.6t3 + 19t2 − 0.5t − 1. The graph shows the cost C in terms of the time t.
(a) Using the graph, which is greater, the rate of change of the cost after 1 hour or the rate of change of the cost after 4 hours?
(b) Explain why the cost function is not increasing at a constant rate during the eight-hour shift.
