Precision Engineering is a perfectly competitive firm. Based on the information above, explain if AVC suggests the functional form: AVC = a + bQ + cQ2. (Draw a scatter diagram of AVC on Y axis and Q on X axis. Fit the scatter diagram with a 2nd degree polynomial trend line.)
Additional Information
This question lies from Statistics and it is about calculating whether or not the AVC or the Average Variable Cost of the firm is in a functional form: AVC = a + bQ + cQ2 and plot the same on a graph.
