In the cost function below, \( C(x) \) is the cost of producing \( x \) items. Find the average cost per item when the required number of items is produced. \( C(x)=4.5 x+9,300 \) \( \begin{array}{lll}\text { a. } 200 \text { items } & \text { b. } 2000 \text { items } & \text { c. } 5000 \text { items }\end{array} \)

nd \( \frac{6}{7} 4 \frac{2}{9} \)

Question 16 The polynomial function \( f \) is defined by \( f(x)=-3 x^{4}-7 x^{3}+3 x^{2}+9 x-1 \). Use the ALEKS graphing calculator to find all the points \( (x, f(x)) \) where there is a local minimum. Round to the nearest hundredth. If there is more than one point, enter them using the "and" button. \( (x, f(x))=\left(\prod_{1}, \square\right) \)
