The graph shown below is the profit function, (q), where q is in kilograms and IT is thousands of dollars. Suppose we know that '(5) = 12. 120 (2.0) (11,81) 1. Interpret the meaning of '(5) = 12. Include units in your answer. (20,0) 2. Use '(5) 12 to estimate the change in profit if q increases from 5 to 5.25 if (5) = 45.
